"text": "Hello friends, my name is Dhahul Vaishanow and I am 18 years of experience in CADCAM software and knowing more than 20 CADCAM software like SOLIDWORKS, Creo in production and manufacturing, even inventor, then in product design I have used inventor, then Art level tutorial course for absolute beginners. So after learning this basic training you will be able to prepare basic shapes which you can imagine or from your ideas. So what you need to do you need to install your Rhino 3D software and then parallelly you need to create design on that Rhino software. So I will teach you topic and then after you need to make the same designs on your Rhino 3D. This is the very basic simple thing. If you make more practice, you will learn properly and you will understand the detail of that tool, particular tool. So here we what is main requirement is you need to understand logic of that command and using that logic, you have to apply on particular object. Suppose you need to create any particular object, you need to think that if this command is going to apply or not. So we will first clear the fundamentals of that tool and then after we will make a practice. Okay, so best of luck for your program and training work. Okay, thank you.",

"text": "In this session we will learn how to extrude the closed planner cow. So first let me show you where it's available. So let's turn on properties, image and text. Now let's see here the extrude options are available here. So this is extrude surface. But inside that there is also options for the cow okay so if I need to extrude cow so there is extrude close planner cow so this is very base and very simple option available here so extrude close planner cow okay for right now what is close planner cow so this is my this cow is closed and it's on single plane so it's all points are lying on single plane so this is non-planar see it's up and down in Z position so for right now I'm doing undo now back okay now suppose if I need to specify height for this option so for this option extrude close planner curve specify section and height so for right now this is my cross section and now once I click on this option or you I can type in Extrude Cove. So by default Extrude Cove is close planner Cove option. Okay, so it's asking for height. So currently when we use this extrusion option, we have these different options are available here. So both the sides, I don't want both the sides. want single sides so turn off this option here both the sides either you can click turn on this option or you can turn off this option. So specify your height so I need to specify 5mm so it's created by 5mm. So this is the option how I can convert my 2D curve into 3D model. Okay, so this is my 3D model using my close planner curve. So if I want to merge different cross sections, so suppose I want to create circle here. So let's use arc option. So center start angle or either we can use start and point on arc option. So this is my start point. This is my end point and I can use this option this way okay and let's trim inside option so select them and use this stream option and click the portion which you don't require so this is stream okay then after you you can see this is the error so you cannot keep this type of untrim portion at the end so you need to solve them because it should be a closed planner cow it should not be overlap or it should not be keep any ends open now this is the join option you can also press control plus j and this is join option so select them and now you can click here closed planner cow and specify your height. Suppose it's 7 mm. So this way you can connect multiple objects and extrude them. Thank you.",

"text": "Okay, so let's import the picture and we will type in picture command and let's select this Practice drawing. Okay type in zero enter and then drag it as you want. Okay. So now in this practice, we will first learn how to scale the image. So first let's see how to scale the image. Okay, so let's create one line. So we need to measure this distance first. What is current size of the drawing you can click here. Okay now specify means create this dimension linear dimension from this point to this point and click here. Okay, it's 19.40. So if I want this distance 23 so what we can do? Just see this is 2d image if model is 3d and you want a 3d scale According to this aspect ratio you need to scale it 3d, but for right now images 2d So for 2d we will use this 2d scale option because I want X and Y both scaling. If I use 1D only this dimension would be changed. So for now I need to click here and let's drag it and make it 23. Directly you can type in 23. So it will scale. Now let's scale this image or see you can also click here or now for now we have I have not show you some options so that's why I am hiding and create this line from this endpoint to this endpoint and let's measure again so it's a linear dimension from this point to this point and let's make it okay. It's if we make it round figure it will become 23. So this is fine. So 20 2.96. Okay. So okay, you can also double click over the dimensions and you can also go to this annotation style. So our current annotation style is default. You can edit it because I want text as a sorry dimensions as a round figure. So here you can set your precision at okay, this is unit and this is see linear resolution. So make it round figure. So you will have proper value. Okay. So this way you can scale your model. Okay, now suppose okay, I want multiple copies of this kind of design. Let's see it in next tutorial that is called array and how to create this design in next example.",

"audio_file": "12%20-%20special%20practice%20drawing%20-%20exercise.wav",
"text": "Okay, in last session we have scaled the picture. Okay, so for right now if I don't want to delete this dimensions what I can do I can move them into layer and I can also bring them back if I need. So select those things which you want to move to another layer. So I have selected first then go to layer option and make it right click here change object layer and hide them. Okay so I have move to layer 4 and I hide them if I want to turn on the display click here you can see there and you can also change their color by clicking on this rectangle and you can click here. Suppose I want this dimension so the color of the dimension would be changed or all the objects on this layer, color would be changed. Okay now I want to work on this top viewport so doesn't matter we need to create this drawing because this is 2D. Okay when you are in 3D you can work even on perspective view. So in future you will automatically learn how to which viewport you need to select or you can also move them after creating on any of this viewport or you can rotate them. So for right now our practice is to create this drawing. fast with the circle diameter option 0. Let us use center option. So, 0 and here is a radius option. So, it is 41. Again, right mouse button 0 enter and 46 diameter. So, I have created two circles. Now, it is 23, 23 diameter of the circle. So, so let's make it 0 enter and 23 is the diameter. Okay, so I have just created this circle. Now there is see you need to always study your drawing for two to five minutes. Observe your drawings. What is it's telling about and how we can create the sequence means which tools are useful for this thing. Okay, so I can see there is one angle line at 30 degree angle and it's intersecting here also here and I think so it's circle means this is a circle of radius 5 and whose center is almost about here. Okay, we can see it. So let's make it circle of 23. Now it's polygon. We also have readymade command for the polygon. So center and radius, this is polygon, but method of creation is center and radius option. So let me create here. So I have clicked center here and drag it as per required. So same way this is hexagon we can change our number of sides to seven eight or five means any sides from triangle means three sides three or more than three number of sides it will ask. Okay. So same way we need to create here the polygon. Okay. So here is polygon center radius. Now we need to snap to center so over over your cursor on circle so it will highlight center so when it highlights center you need to click here don't go there you can directly click click here and it will automatically snap to that center you can also click here or you can corner of polygon or you can also type your value of the diameter. Okay, so for right now just click here because we already have created this circle. Now move to the hidden layer because we don't require circle. Okay, so this way I have created this polygon. Now I need to create this angular line. So we already have seen that we need to create angular line. So line angled. Now go to this see we need this center intersection so we can see it's radius of 5 so create this circle at this point okay it's not a snap properly circle and radius we need intersection so turn off the center option and let's turn on intersection this is intersection okay so O snaps are very important if intersection is highlighted then only it will show you that option. If it is tick then you can highlight your intersection option. Now it's radius of 5 so click here and type in 5 enter. So this is my circle. Make sure its center is here. See I can see this dot. So that's why otherwise you need to show this dimension with the arrow in dimensioning method. So you can justify that it is proper value. Okay. Now I need to create these two lines parallel. Okay. So for that it's distance of two. Okay. So I need to create this line as a offset. none we don't require any cap and again right mouse button select here and click this side now I don't want this line so move it to another layer okay so in future if I require that back turn on that layer so we can work on that again so don't delete them okay now I need to select all those objects and go to trim option and trim unwanted geometries. I think so these three are not required. Let me check again it's going out of side okay and this portion. I think this is the shape point. Now, okay and select these four options. Okay, this is my selection windows left to right right to left. Okay, so we already I already have shown you so now which four entities are required for the number of pattern select them. Now for creating. I have option of array so array polar is the For circular pattern so circular pattern it is called polar. Okay, so now for circular we need to specify center So whoever your cursor here, but our center option is unmarked. So mark them mark it and go to boundary Click here and now number of items you can see it's 1 2 3 4 5 6 so type in 6 enter okay now you can also change this angle to fill option so for right now we are just selecting 360 degree and make it done okay so see you can see this preview still I have options to change this so fill angle I can change to 180 so in 180 you can see that this array has covered this 180 degree so fill angle is right now 360 degree okay now let's make it done and select all of them and use stream option cut remove that unwanted geometries portion. Okay, so this is fine. Okay, thank you.",

"audio_file": "13%20-%20extrude%20curve%20in%20detail.wav",
"text": "Ok, once we create this 2D sketch, so need to convert this objects into 3D model. So what we can do? Ok, see if I want to select all those objects inside this circle, so what we can do? We can use this left side to right side selection window. So in that window only objects which are covered in this crossing window means in this selection window are selected. So this is selection options and now you can join them. So here is the join option. So we will make a loop. So this is outer loop and this is inside loop. Okay now go to perspective and select them all and use extrude option. So extrude cow as we have used before. So we can extrude for 5mm and now make shaded view. So you can see your extrude is perfect and all the cows are not overlapping or they are not open from anywhere. So if you are using extrude cow command so you need to follow two things. Section must be closed and entities should not be overlap. Okay so what extrude curve will do? So, it will follow same section and same path. So, we can understand extrude curve in a such a way that it will create rectangle into same path. See, these sections, suppose if I have created this kind of section, so it is extruding means once we type in extrude cow command, it will follow the same path. It's not turning. It's not turning about any path cow. Yes, we have another option inside of extrude solid options, but still it has a restriction. See we have another option extrude cow Cove. So for right now ExtrudeCov is following same path up or down. It's not turning. So for that we have another option and we will also see this option in next session. For right now once we complete this kind of exercise or closed sections we can generate 3D from this 2D object. Okay. Thank you.",

"audio_file": "14%20-%20sweep%201%20and%20extrude%20along%20curve%20-%20set%20view.wav",
"text": "Okay in this session we will see what is new command of extrude, call, along, call and sweep one will do. Okay so this is a very important option sweep one and it will be more useful while we are creating you know a variable path. So here is the same path, but if I want to use variable path, so let's see how to use a variable path. Okay, suppose we are going to front view and now we have seen line, circle and rectangle options. Even we have also seen one polygon option here we can see we will see this curve creation okay so suppose I have used this option curve interpolate points so if you want to create okay let's go to front view and if you want to okay let me check now let's go to front view and if I want to use this option control interpolate points. Front. Okay. I have just created top option. So see here I mean front viewport and its front viewport is activated. But here I need to set V as a front. Then only I am able to create the ship. So sometime if this kind of error happens go to means if I am on front view here it's typed front viewport and if front viewport is not set here so you can set it from here. So this is very important option set view. Okay so right now I need to create this option cow with the interpolate points option. Suppose I have created this kind of shape. So see it's variable curve. If you want to change its curvature, so you can also set click on the curve, you will find these points. This is called control points. So this control points can be adjusted accordingly and you can adjust them as you want and then you can okay now for this case we are going to define one rectangle as a cross section to use this option extrude curve along curve so we need another curve to extrude so let's create a rectangle with the center option so click here and click your center. Then adjust your length and width. You can type your length and width as a seven. Okay, five by seven. Okay. So now suppose I want to use this option, extrude Kavalon Kav. It's asking select cows to extrude. So this is this cow I want to extrude, then enter and select path near start so suppose I want to extrude on this path see it's use this option Extrude Curve along Cobb, but this is restricted. See, it's narrow here, it's broad here, again it's broad here. So this is not the proper way to create this kind of shapes. But if you need such kind of shape, you can use this option. Now let's go for the better option. Okay, so now let's see if I want to create another new copy, I will keep pressing Alt key and then use this translation or a move option. You can also use another move option from here. So select your object and then click here transform click on move. Now it is asking for points to move from. So this is my base point and now this is my target point. So I want to move here. So now here if I am using the same way, same creation of rectangle, I need to adjust this angular according to tangency of the curve. So if I am going to create the rectangle this way, this is not the good tangency option. I need to set it according to curvature. Okay, so this way I can adjust this arrow on this cow. So this is little bit okay for this curvature setting. But let's set it apart. Okay, I can use another option that is called sea planes. This is very, very wonderful and very important option. So select this option set sea plane perpendicular to cow. the So now set it center here Okay, and if you want rounded corners you can you click on this option After creation of the rectangle it will ask for the rounded corners so you can set your rounded corners accordingly, okay So now if I want to follow this rail with this cross section We will use this option sweep one rail it is asking for the rail first. So this is my rail always path is the rail and now it is asking for the sweep shapes so this is my sweep shape then enter and enter so you can see now it's perfect from all the angles go to front view and now you can see it's in the same dimension from top to bottom and it's according to its curvature. So it's ending here it's not like a flat means it start and end is the same but this has the option according to the curvature of the curve. So it will set objects as per the curve curvature of the curve. Okay now we will see few other options of the sweep one in next session.",

"audio_file": "16%20-%20cplane%20fundamentals%20and%20Rib.wav",
"text": "Okay, so in last lecture we have used C planes. So we need to understand the fundamentals of the C planes, how C planes are working. Okay, so if I have created any objects, suppose I have created any readymade, these are the readymade 3D objects. Extrude is the different means it is used for creating 3D shape from 2D object, 2D shape. Okay. But these are the readymade 3D shapes. So these are the methods to create this box. So suppose if we have corner to corner and height, so when we define this corner to corner and then height, we can use these kind of options readymade options. and we can click anywhere on that curve and we can then define our cross sections as per our requirement. Okay, so this is Cplane to define perpendicular to curve any perpendicular point on the curve we can use this option. Okay. And after creation if you want to bring back original position so we can use this option set Cplane World Top so by default it will bring back that home position okay but for this surfaces suppose anything I want to create on this surface so manually people are doing this kind of shape then they are using this gumball for rotation and this kind of rotations so this is not the proper method and sometimes it can create error. So here is another option for setting C plane to surface. So you need to select your surface and you need to select surface to orient C plane. So this is my surface. Then you need to click two times at two corners for setting X. So accordingly Y will be set and perpendicular to this surface z will be set perpendicular. Okay, normal to that surface. Okay, so this way we can set c plane on this surface and then you can define your any cross section suppose I want to specify polygon star. So this is polygon star option and you can click here then drag it. Okay now keep pressing shift key for temporary ortho mode on then set this star position So now select this cow and use extrude cow option Extrude cow, okay extrude close planner cow and you can now it will be extruded according to that C plane so X C plane is Okay, always extrude the cross section the for the x y will be set accordingly. So here suppose I have created one circle and now I have specified some distance of 5. Now if I have changed something I have made something change. So now let's see the extra option of the one kind of Reap up to selected boundary. So this is very wonderful option. You can use this option for different kind of Reaps. So it's one kind of Extrude but it is defined as a Reap. So you can set cross sections as per your requirement using Reap command. Thank you.",

"text": "Okay, so we have learned different kind of C planes, extrude sweep options and few cow modeling options, cow creates cow creation options. Okay, now let's see a few options from this transform modifier tools. This is most and most important tools. If we don't use these options, we cannot reduce time creation of any object or we cannot reduce it means it will make our task so much easy. So let's move this all the objects in layer 5 and turn off the layer. Now bring back this C plane to top. Suppose I want to zoom in go to standard and here is the zoom all option zoom extent and you can also type in here zoom sorry it's zoom Z for means Z double O it's zoom enter and say sorry let's make it zoom means Z enter and extent it will adjust the screen but right now we don't have any object so Z enter A enter so zoom all and then extend but this is fine for right now let's make it a zoom window this is the window we can zoom in and we can also particular zoom this option we can also zoom in by roller if we have any object created then these options will working differently of the zoom objects. Okay for right now we have not create anything so that's why these are working in a different way. Okay now suppose we have created one box corner to corner so type in zero enter and make this way any simple box. Okay now on the top of that let's also see this option ellipse. ellipse from diameter from center it will create symmetric means suppose if I have clicked here as a center and make this much distance so it will create symmetrically both the sides. so we can adjust distance means first x distance and then second y distance. So, two different distance we can specify and create this kind of old ship. So, if we specify same distance x and y it will become circle, but ellipse is different from circle. So, if we need this kind of shapes we can define circle. If I want to create anything here what I can do I can set C plane I can also move this object which I have created here and I can move this object to here. So let's make one point at the center. So over your cursor make sure your center is on. If it's highlighting its center, it's not highlighting right now. So let's make one line from this midpoint. Okay, it's not okay. It's highlighting midpoint Now make one point at the center. Okay. Now I want to change this Objects center point to this point. So how it can be possible? Okay, so let's Select the object use move now point to move from so I want this point means middle of this ellipse so it's highlighting center so click now it will hold object from that center center point and then you can click here so this way you can move your object from one point to another point. But move command will move your original object. But if you use copy, so if I need this object, but I need another copy, use this copy option, same procedure point to copy from. So this is my point where I want to copy from and you can Extrude Cough to see the curves. So suppose let's go to this Select panel and click here. This is selection of curves and you can press Ctrl plus H for hide. Now you can go to Ratis or Render option. This is the object you have created.",

Okay now if I let's go to top view okay if I want four or five copied particular angle so we can use this rotate option okay so what is rotate so select objects to rotate this is my object which I want to rotate okay I want copy yes I will check mark here yes center of rotation so whatever your cursor here when it's highlight center you can click there and then you need to specify first reference point so means I want to click here at zero means on this circle or here then you can drag it suppose if you want at 90 degree you can type pin 90 degree suppose you want to at 45 so it's 45 if you want at some different angle suppose it's 245 or 235 so let's make it 235 so you can specify your angular position and click or you can also click anywhere okay so this way you can rotate your objects with a copy and suppose if you want rotate these all the objects together you can also press Alt key and click here this is the rotation axis so this is second rotation with the copy and you can I have keep pressing Alt key then I have clicked on that axis around rotation axis and then click 90.

"text": "Okay, so let me show you different scaling options which are available here. So scaling are very important. Okay, so suppose let's let's create specified circle with some specified radius value. So suppose this radius is 10. So I have created one circle of 10 mm radius now let's make it okay another copy add some distance so keep pressing Alt key and click on this arrow specify dimension of 25 and again keep pressing Alt key and dimension of 35 okay so we can generate multiple copies now let's make it little bit 5 mm that side so it will broke the history so if we make change on this circle it will not effect this circle for right now I have created copy of this circle from this circle so if I make any changes it will effect on this circle because of record history here it is mentioned I will show you this later but for right now if dependent circle if we move it so for So it's record history, break record history. Now what we can do, we can scale this way. If I want to scale 1D means only single dimension. So we can use 1D option. So suppose this is a circle and I want only this X value change. So select circle then enter and select those two points which you want to change and specify dimension. I want 8 mm so you can directly type in 8 if you want something different value so suppose 12 so this is 12 dimension is 12 okay now suppose if I want to make changing both the directions all together so what what you can do here is already boxes are given so you can directly click here and make it 0.5 so this will become half and if you want to make change in both the boxes altogether half means you want to make half of this value so what you can do keep pressing Alt and Shift key then click here it will create new copy with half means 0.5 means half value. So this way you can create two circles means scaled circle in a small size if you want to make it double. So what you can do select this circle or object which you have created then keep pressing Alt plus Shift key and click here and type in two. So it will make a double value, double size. So 12 becomes 24 and another value becomes value. point it will make change in all two directions. So you can also specify your value suppose if you want 12 so it will become 12 value and also make change in y direction. So this way you can create means make change in x and y directions. Okay, so if we have 3d objects suppose we have if I have extruded this object extrude cow and specify height of 10 mm. Okay, see if we have any closed section inside of another closed section and if we select both of them and if we apply extrude cow both the circles will be extruded and inside circle will be automatically subtracted from the outer side. So specify 10 mm here and now you can see in shaded view. select the base point select the target point and now you can specify 0.5 or 0.25 or 0.75 value so this way you can reduce your scale okay so this becomes too much small okay let me check the value select this point to this point okay now you need to specify these dimensions okay so let's make 15 so this dimension will become 15 and accordingly all another two axis y and z will also make a change. Okay. Thank you.",

"text": "Okay, so let's learn array. So if we have something kind of pattern number of patterns on any object, so how we can create it? So let's first make circle with the zero enter and it's the center of the circle and specify diameter value. It's 12 diameter. Now let's select the circle and extrude cow. Okay, so we already have seen the extrude options. Both the sides and solid we have capped ES and now specify 1.5. So this is my total height is three. Now let's make something sphere kind of with the center and radius option. So let's select the highlighted objects net point specify radius radius value it's 0.75 so total is 1.5 yeah. So now select this sphere and specify your command array polar. So array polar what will it do? array polar will create circular copy so you need to specify your center point. So for right now I already have this circle available. So let's do this option array polar. Now center of polar array. So I already have circle available here or you can create new circle or you can specify any other center. So it's depend on your result. What result you required. Okay. For right now you need to hover over your cursor on this circle it will highlight the center point make sure OSNAP is on and center is checkmarked so hover over your cursor on this circle and click there so it will show you the center now you need to specify number of items for right now we are taking 22 and angle to fill it's 360 if you want to fill only 180 you can also specify 180 keep preview yes now may click enter it will show you preview before confirmation so you can still change your values okay for right now let's make it 23 so see it the gap has been reduced. Now just click done if it's okay. So you can see there is a circular pattern. Okay, so see if I have selected this circle and if I use the same command array polar and for this time center of polar array, I'm just specifying any another point. Suppose it's here. So let me click here and means any point on the screen anywhere. So now this will create circular pattern with this distance. It will create one circle with this distance and make a copy make array. So this way it will create circular pattern. So now if you understand the concept how array polar will work. So now for right now let's select all these cows all these spheres and I have just selected original one it's because of record history. So don't select this one only select these objects and it will show you and then it will complete the command ok. The same way see suppose I want to copy this curve from this point to this point means from the center to top center here I want to make something pattern on this H so let's make copy and hover over your cursor on this curve it will highlight center and hover over your cursor on this edge it will also highlight center so I have copy this curve from this point to this point. Now let's make another object like we can make a torus. So select here it will create one smaller circle and then you need to specify your diameter of your circle. So this way we can define torus. So I want to make circular copy of this object. So select now this time I'm using array cow. So this is array polar and this is array cow. So you need to create cow before means before this exercise you need to specify your cow means before using this command array cow you need to specify your path or either you can call path cow. So I already have selected this object then I have applied this command and it is asking for the path cow. So select this path cow. Now we already have something defined value it's 25. So select it and make it change to 26. If it is okay then please done. Now I want to Boolean difference. So select this object and Boolean difference you can also use Boolean split as well. It will create three copies original this one and another split trade Split trade one. Okay, we will see it later if it's question for right now select the bigger one then enter and select all those upper objects and I don't okay cow is not selected only Boolean objects will be selected okay I don't think it's Boolean no it's done this is good okay so see this is the result now we can check it in render see this way you can create such objects okay and let's make one more example with the path code suppose this is my going to pull it point this is my path and this is let us make another new shape. Let us make truncated con, select the endpoint, specify your object values, parameters. This is the truncated con. You can also make larger scale with the key pressing shift key, click on this boxes and make it 2. So it will double the scale. Okay. Now select this object and press array cow and select the path cow. You can also specify your base point if you want to specify some different base point by default it will take this starting point. Select the path cow. This is my path cow and see you can see the preview. You can also change distance. You can also change number of items, let's make it 30 and then done. So this way you can create path array and cow array cow and this is polar. Thank you.",

"text": "Ok, so let's import this photo with the picture command and then select this photo, split command, select this rectangle and then press enter. So we can split this object. Now select unnecessary objects and move it to another layer. So we will we already have seen this option how to move this layer and rename it with the extra layer name. Ok, and now you can turn it off. Okay. So now first of all, when you have any object to create first observe your object or model properly. What is the main overall dimensions and how you can start. Okay. So here you can see the overall design have a T consider these dimensions are in MM. So here you can also see that you are given you have provided these units in millimeters. If you have not set your units, so type in underscore options command here and go to this unit system. It's available here and set your units as a millimeter. Okay. And display precision, it's round figure into one one so for right now it is okay now you can move your image to another layer so accidentally you cannot means it cannot move or it cannot delete so I have select this photo move it to another layer and then lock it okay so you can also turn it off and on later for right now let's study this model. Okay so here it is 80 mm given and it is from the center to the center is a 17. So let's make first this line and this line. Okay so let's first make this line of 70 mm. So here it's a line type in zero enter and make ortho temporary on and type in 70 and then press enter in this direction. Okay, now enter. So this is 70 mm line and from bottom side it's 80. So we will use line from midpoint. See logic is very important if you know the commands but your logic is really very important and now see it's line from midpoint. So for 80 you need to specify 40. It will make the double. Okay. so I will repeat last command so for that I will press right mouse button and then again hover over cursor on this circle But make sure your center is checked on Okay, turn off ortho if it's not required then hover over your cursor on this circle when it highlights center click here and then specify its diameter as a 30 Okay, 30 yeah now see it's perfect with this center. Now this is the same copy available here. So we will select these circles and let's use copy command. We need to specify base point. So I will copy the command from this center and I will click here. So it will create copy from the center. Now at the top here it's a small circle its diameter of 16 and another is a 6060. So let us create two circles one is diameter having 16 and another with the same center but diameter is 16. So now let us connect this outer circle with the outer circle. We have a very fantastic option available here. It's tangent to two cows or we can also click here tangent from cow perpendicular to cow. So these are the all options for this tangency. Let's use this option. Let's try. Click here outside option and this another option. So this line is tangent to both the circles. Same way. Select this side. Okay. Now here we have a radius of 16 but it's in tangency option. So for this case I have option of radius it's 16. So we can also use this arc, tangent-tangent radius and let's click here this is okay may turn off the center so it cannot connect with the center. This is my first tangency, this is my second tangency and now it is asking for radius. So, it is a 60 ok. So, this way we can create this circle at this side ok. We need to specify side at the last moment ok. So, the outer base is having this much of closed section and having 10 mm thickness. So, this is not required for right now. And let us go to perspective. So, we can see this. This close and this means basic cow modeling work. Now, I need to extrude 10 mm for that I need close section. So, let's trim unnecessary objects. So, for trimming we need to select all those objects which are connected and let's click this option. So, we already have checked the trim option and make sure it is connect perfectly but see here you can see there are open ends also select this. Let's first trim this portion sorry and then zoom here and let's trim I think it's connected perfectly yeah okay it's join again select this option and join so if it's not connecting perfectly you need to again recheck if it's having it any cow have any opponents now select this circle select this extra circles and select them and use stream option select unnecessary portion okay so we have trim unwanted portions okay so see for extrude that is one condition it the section must be closed so this is now select all those curve which are creating closed loop and then make it join. See we consider we are on this plane and it will go backside as a 10 mm. So let's use extrude curve option and turn off both the side option make it solid and use it as a 10 mm and make it shaded. See if it's coming this side you can use minus 10 value means negative value so it will go reverse side. Now I want to extrude this circle only of 60 mm diameter. So again let's create circle and I want to create circle on the front or if I want to create circle here see by default if I am going to create here it will create on this plane but this is not the my current orientation okay we can also rotate it with the gumball but for right now we are going to use c plane for c plane we will have this option set seaplane to surface. Okay so this is my surface and set your seaplane accordingly. Make it sure it's straight so turn on ortho or you can also keep pressing shift key it will turn temporary turn on the ortho. Okay now we can create circle perfectly on this portion and we will have this same outer portion. Now extrude it, we also have four circles with the minus means subtraction, we will subtract it later, but right now just extrude it. We can also do one thing, see there are four circles on this circles diameter means on this 40 mm circle and there are four circles on its quadrant. Let us make it together. So, let us again create one circle of 40 mm. There are four circles here this is my make sure your quadrant is turn on turn turn off these not invertex, okay, make, okay, create these four circles of 10 mm diameter. See, it's 10 mm here, okay, so let's make it 10. Now, you can select the circles and use copy command and now I want to copy it from this center. So, for right now the circle center is on quadrant. So, we can also click there and click wherever you want to place these circles. So, I am selecting this outer circle and inner circle. So, for extrude curve option have one condition. If there is a closed section inside of this closed curve, it will automatically remove this inside material. I have not selected these circles this extra circles. So, it will only work on the selected circles. Now, we can extrude it with 10 mm see it is 20 here. So, 10 is already we have given. So, in this direction we will apply 10 mm extrude curve and 10 mm this side. So, 10 mm see the same method we will apply here we can we will create these two circles and extrude in front direction. Okay, so let us over our cursor make sure your center is on and one center is on you can create two circles you can also make copy or create another circle so copy from center to this center okay now select the four circles you need to understand how extrude works and where we can apply and then you can easily create these options now you can use extrude curve and specify 10 mm dimension okay, this is our model is ready and let's make it render. Thank you.",

"text": "these dimensions to another layer. So select the option or object and then right click on that layer. You will find these much options. Now select change object layer. You can find here in Rhino 8 it is little bit change but in Rhino 7 you can find here change object layer and then you can rename your object. Suppose I want to make all the geometries on another layer. So just right click on this layer and change object layer and you can turn off and turn on the layer. For right now what my planning is to do I want to now make another rectangle. So for that let me create one rectangle. Type in zero enter here and Make it little bit and rectangle rectangular view. Okay, I don't want to see these geometry So instead of deleting I can turn off its layer so I can hide now You we already know extrude cow option. So this is my extrude Cow or stood close planner cow and specify your the like this way, bend. So we need to define full line. Okay, we will see both the options. So let's first make this middle point to the middle point. Okay. So for this case, we will keep open four windows, means these four reports. For the selection of this spine, we will use this window and then for bending, we will use this window and then for bending we will use this front window. So let's first select this object go to transform and use bend option. Now it will ask the spine so it's like selecting axis so this is called spine. So start of spine and end of spine is here. Now I have selected both the points and see it cannot Bend properly in this perspective Direction, so I will take it to front window and now I will specify my band angle see this way I can bend Okay, see if you turn on this rigid option it will Bend like this way so it will keep rigid So turn it off and now you can specify 15 degree or as you required 35. So 35 is the angle and click here. So this way you can bend your model. Okay this is first option. Now let's make undo. Okay. If I want to make it symmetrical band, so I'm just deleting this axis and now make center lines. Okay. So for center lines, use this middle to middle line and then create one middle line from this point to this point. So the things will created properly means in proper symmetric way. Now select this option and go to band option turn on symmetric option otherwise it will bend only in one direction and it also affects the second direction. So, make sure it is symmetric turn on and you can specify your angle. So, this way you can make angle in both the directions. We just need let us make it again. Let us make a band from this point to this point. This is our spy In a proper way your clicks are okay. It's not getting proper shape after Limit to spy. Yes, this way it's getting little bit round, but in before it was getting little bit straight. You can specify your angle value. So this is the band in both the directions. So this is symmetric band.",

"text": "Okay, so here is the option that is orient. So if I have any object available and if I want to orient it means if I want to change its position with the scale without scale, so there is one wonderful option that is called orient. Okay, so see we this is our training for absolute beginners. So in next part two 2 we will cover more sub options in detail but you need to clear these options first so that's why we have covered all those options in for the beginner level. So after this cover we will also clear all these options in next session there are many options available in detailing of surface and there are more options are there so we will see it in intermediate level so for this thing you need to clear these basic options if we have selected any object then we need to suppose orient to this point these two points should orient at this line so how we can orient it so let's select object then click on this option that is orient with the two points. Once you click on this option it will ask for the copy or scaling. If we want to scale only one direction means if I only want these two points on this two point with the scale so I will make it scale with the 1D option and let's make it new copy. So reference point one is here reference point two is here on the object which we want to make orient then target point is here and second target point is here see it's only increase its length because I have only asked for the let's see this happens because record history option is on so this is the child object. We will see it in detail in later options. Means in part 2 because RecordHC is you know depend it will make objects dependable. Okay, so suppose now let's make it undo. Move it little bit back side. Okay, now select the object and go to orient with the two points this is my first reference and second reference see here I have used only one direction so this direction means these two points only will get oriented on this point ok now make it done if let's move this option and it will break now this is not dependable it the warning was for the record history was broken okay now if I want to make change in 3d so let's use this orient option with scale 3d command 3d option so this is my first reference this is my second reference and this is my first target and this is my second target okay so it is also make change in height. So, now complete that object, okay, complete that command. So, this way we can make this is 1D and this is 3D option. So, suppose if we are going to use this option orient with the three points. So, we need to specify three points in the same way, but we can also make scaling yes and no we can also create a copy yes and no okay so right now we have just turned on them first second and three points we need to define and suppose this is my three reference for third direction I have also make this line so this is my first target point second target point and this is my third target point okay okay third is for direction. If it is downside, so means if we have created any line bottom side, so it will go bottom. Okay. So how we can create it? Let's go to here line vertical to see plane and let's make line bottom means bottom direction. Okay. This is our C plane as you have seen in previous session. Let's move this object here. Okay, so for now let's select this object, use the orient option with the three points. This is my first, second and third click. Okay, so same way, similar way this is if we don't want to scale it, make it no. This is my first click, this is my second click and this is my third direction. So it's going bottom side. See. So, all those three points are oriented to this point without scaling and this is with the scaling and variable options. This is with the 1D scaling, this is with the 3D scaling and this is with the, this is also with the 3D scaling. So, we can make more way orientation, but make it clear and do the same practice on your own object",

"text": "Ok so let's see this is very wonderful option that is called twin cows so if you have two different curvature kind of cows so this is my first cow and this is my second cow. Ok now you want to create in between cows the cows will go through this curvature to this curvature and I want five different cows in between them. So how we can create those cows? So we will have this option Twin Cows. Okay, it will ask for the select start and end cows. This is my start cow and this is my end cow. You can specify your numbers. So I want five numbers and you can click done. Okay, now suppose if there is one object available let's make it one box corner to corner and then height. Okay now if I want to cut this object using this kind of option so I will go to top view again I will create these two different curvatures. Okay now select them and type in twin calls it will automatically add calls to there. Okay now I want required three calls then done. Okay now bring them at some height. So move it. You can also specify specific height. Okay. Now suppose I want to cut as a wire cut ocean. I want to cut something from this object. So there is a command called wire cut. And see I already have selected this object. Now it is asking for select object to cut. So I want to cut this object and now press enter and bring this depth means up to this midpoint or something height you want to define. So for right now I am specifying midpoint. See here there are the suboptions. If you want both the sides keep all you want to keep all the objects after cutting. So you can keep this option yes and if you want to specify any depth so suppose this is the depth of this is my depth for this particular portion cutting so click here and now you can see this object we can remove so this is cut object option is there so this is called wire cut okay similar way we can also use both the cows together. So let's move this apart. Okay, now select this option and this option on particular this this surface. So let's make it 90 degree. And now I want to cut this this two curves and select object to cut enter specific depth and make it little bit thickness so see this way keep pressing shift key and you can select multiple objects so this way you can make wire cut cuts okay",

"text": "Now let's see how to import picture. So type in picture command here click here and type in picture and let's select this image. You can type in zero enter and okay you can also select your viewport. Suppose if I want to make means import in this viewport so click here and drag it as much as you want to scale it up. You can also scale this image as per your required size. We will see it later. Okay for right now we are just creating this line work for angle work. Okay. So here we need to use first our normal basic line work. So type in zero enter and specify it's a 20. So 20 just click and now it's line segment so it will stop there. Okay if you want to repeat your last command just make right click right click of your mouse right mouse button or you can click here and click this way and type in 10. So it's 10mm click upside So it will create line of 10 double click here or if it's highlighted press control plus M for maximize So now this viewport is maximized you can switch over from these shortcuts. Okay, so for right now we are on to front viewport now we need to create this line at 125 degree. Okay, so it's 125 from here. So we have this option available line angle. Okay. If you are starting this command, click here, it will ask start off baseline. So, okay, first understand Rhino is working on clockwise and anti clockwise direction. So if this is 125 from this this direction, it's clockwise So you if you are creating baseline from this point to this point and now if you are typing 125 see it's creating this way so it's creating 125 form here this vertical line and if you are creating same line see from this point to this point but this time you are specifying angle minus 125 so it will reverse the direction and now you can create your line on this angle okay so for right now we are just specifying 12 mm okay click here again this is also 125 and this is 10 but see you can see this is mirror from this point. So from this point it's mirror work. So let's select these two lines for multiple selection. Keep pressing shift key and click another line. Now here we have the option of mirror and you can also type in command MIR so mirror is the command now click this point to this point okay see if it's not matching there there is some errors are there so let's check it again this is not proper symmetric work okay so there is some error in this drawing let's do it again but in reverse direction. Okay, so from here there is a line of 10 mm. Okay, click here for creation and now it's 125 in this direction. Okay, so make line angle in this direction. Okay, it's asking for baseline from this direction to this direction. Now I'm typing 125. Now specify 12 length. Click here. See it's not connected. So this length is given. It's not proper. So for right now I want to connect this line as per this dimensions. This is not connecting so maybe it could be a different in length so for right now I'm just using connect command to connect these lines okay so click this line and this line it will connect automatically now let's measure this line dimension if it's okay it's 12.21 so it's not round figure but it's 12.21 if this is 125 this is 10 this is 20 so this length of the line will be 12.21. Okay so now let's measure this dimension as well it's 10 it's 20 and now let's measure angle dimension so from this line to this line it's 125 and this angle so everything is perfect except this length thank you",

4 - circle and use of Gumball.wav

{
"audio_file": "4%20-%20circle%20and%20use%20of%20Gumball.wav",
"text": "Okay, now let's understand how the circle command is working. So we will see the details in few means other examples later on for right now we are just starting up with the circles. Okay, so if I need to create any circle so you can click anywhere means directly you can hover over your cursor in any viewport. These four are the viewports and type in zero enter and then see if I want to change my orientation of the circle. Let's move this toolbar for here to see the orientation change. Okay, if I'm creating circle from top view, you can see the result in perspective. This is our 3D view. Okay, so here. For right now my cursor is in top view. I am just moving to front viewport. See its orientation is changing in perspective viewport. Now I am moving my cursor to right plane. Why I am showing this? Because you need to select right plane to directly create a circle in proper position. Suppose if you want to create circle on this way, so it's top position. So we can create our circle on using top viewport. Okay, now you need to specify diameter or radius. Radius is the half value and it will double the overall dimension. So if I'm specifying diameter of 12 your mouse. So you will understand how this screen will move in 3D rotation. Okay, in top viewport, in front viewport it will pan. The same right mouse button will pan here because this is not 3D. This is our 2D viewport. But if I press control plus shift and right mouse button it will change its convert into 3D movement. Again if I want to set it back Click here set view and this is our right side viewport. So click here in right click. So see this is our right viewport Okay, if I want to make another copy of this circle, you can use this gumball. Okay, these three linear direction these three rotational direction and these are the scaling directions scaleingsaling. You can turn off gumball from here. Suppose if I want to create another copy at 90 degree angle, so keep pressing Alt key and click on this rotational axis. It will rotate in this direction. So keep pressing Alt key and click on this axis and press 90. So this is 90 degree rotation. If I am selected this circle I have pressed Alt key click here and 45 it will create circle at 45 degree. So this way you can create multiple. Suppose I want another copy keep pressing Alt key and 45 so this again becomes new copy of this circle. Now in next lecture we will see details in Gumball for right now we have just used this circle option. Let us show me another option circle with the three points. So if I click on any three points, suppose this C circle having quadrants. Okay. There are four quadrants. Let me show you. This is circle and there are four quadrants 090, 180 and 270. So if I want to start any line from the quadrant. So now let's see O snap option. If this option is turn off your object would not be snap. If you want to snap at the quadrant, see it's highlighting quadrant point. So you need to turn on O snap option and you need to tick this option here, quadrant and then click here. So you can create your line and turn off ortho mode. So it will not lock in straight position. Now your line is free to move in 360 direction so for right now I'm just clicking here okay so this way you can create line from quadrant to quadrant okay",

"text": "In this tutorial we will learn this new features of this circle. If I want to create circle with the three points, let's click here and I need to click on three points. Suppose this is my first point. I have shown you four corners of the circle. You need to start any object means any command and just hover over your cursor on exit 0 90 degree 180 and 270 so it's 360 degree circle but there are four quadrants exactly passing through that 90 degree position okay so for for right now I'm I'm clicking selecting quadrant options So make sure your O snap is clicked and checkmark your quadrant option. So first click this is my second click. Okay, see it's here on quadrant and this is my third click here on this third circle. Okay, so see you can see my circle is passing perfectly through that three clicks. So this way you can create your circle with the three point and for here. Now I am using circle around curve. So circle around curve means you need to select your curve. This is my curve and now center of the circle. So suppose you can specify this circle anywhere on the means this specified curve. So suppose this is my center and now drag your cursor or you can also specify the radius value. Suppose it's 2.5. Let's make it laser 1.25. Okay. Now again I want to connect on this upper side. So I can click here and now specify your second value suppose it's two radius of two so this way you can create your circle around cow and now you can make different for size of circles and see this is my third circle now specify 1.75 and here it's okay let's let's keep it up to here we will use this example for the 3d cow. Okay, so and fourth example is tangent tangent radius option for the circle. So you need to specify two tangent points. Okay, I have just used this rectangle. This is very simple option corner to corner. So in rectangle you need to first click anywhere and second click. Okay. In next session we will see the details how to create rectangles with the size and all details. For right now I want to use this option. We can also create lines but for right now I have selected rectangle which is join lines. Okay. So here tangent, tangent this is the sequence of your clicks. First click is taken as a tangent reference, tangent reference then specify radius value. So suppose this is my first tangent option, this is my second tangency option now specify your radius value. So it's three. So now it's a circle of radius three. Okay, so this way you can create tangent tangent and radius option. Thank you.",

"text": "Okay now next session we are looking next options for the creating circle. Okay, see this is very wonderful option which is very new. Okay, this option tangent to three curve so we need to click on three tangent option so this is first second and this is third option so this way we can create a circle tangent to three lines. Okay, in next vertical to C plane center and radius. So this is a very wonderful option. This is C plane. We need to understand C plane. In next session, I will explain you what is the C plane currently just understand the grid showing here. It's our C plane. We can change C plane. We can use C plane to create multiple 3D cross sections C planes it's actually understand sketching plane. So C plane is equal to sketching plane how to change it I will explain you later in next session. So for right now it's vertical to C plane means it's vertical it's normal to C plane. So let me move these circles. See this is my C plane suppose this is my C plane and now it will the circle which I will create that will be a vertical to that C plane so let me show you the use of this smart track so currently if I'm highlighting this midpoint and I'm over over my cursor here but it's not showing any tracking lines so if I turn on this Smart Track option and I hover over my cursor here and if I track this see you can see this line infinite line is creating on that point and see now don't zoom in zoom out just move your cursor here on this midpoint and track this line I have not clicked anywhere and see it's intersecting here. So I'm just going to click here and see it's creating vertical to see plane means this option. See this circle is creating vertical to see plane and now this is my center where I have clicked. This is already vertical and this is my radius is up to this point. So see this way you can create circle. Suppose for this one let me click here okay vertical to C plane but I want to specify my center point so let's track this line here. Track this line from this quadrant. You need to hold it for one second so it will track start tracking click here and drag it and click here so this will understand the radius up to this point. Okay so this is very special and very unique option which Rhino have for knobs modeling. Okay next the similar option which is vertical to C plane for the line. So see by default line is creating on this C plane. So it's lying on this C plane. So currently this is my C plane and if I want to make vertical to C plane. So this is the option and click here it will be a vertical line to the C plane. So this is vertical line on this C plane. So, same way this is the circle vertical to this C plane got it. So, these are the options related to C planes. Thank you.",

"text": "Okay, so let's learn cow creation options. So if you want to we have seen the line option we have seen the circle and if you want to make this kind of curvature options so we have the options available here. So first let's see control point cow. So if you want to create any cow this way see the cow which is creating is not passing through our clicks but instead of that it is making control points. So once you select any cow it will show you the control points. So using the control point you can create this kind of cow. Another option is cow interpolate points. This creation cow method this show the control points of that cow by default any cow you select it will once you click on that cow by default it will show its control points and you can also edit them. So if we want to make cow, let's turn on the image. Now if I want to trace this photo, first let's log the layer and in this case if I am going to use control point curve, see this curve cannot pass through our clicks. Got it? And let's make the change in color so we can see it properly. See it's not passing through our clicks but instead of that if we have used, let's move it little bit. If we have used this option curve interpolate points, so you can see it will pass through our clicks. So we can properly trace our photo or means whatever curve we can trace. So this way this option is very useful. Okay. And third option if we need to use the second option see cow through points it's available on our right mouse button and if we need to use that option we first need to create our means points different multiple points. So just click the points wherever you want to pass through your curve and then step by step. See after practice you will understand how to use this option. You need to make right mouse button. Left click is control point curve, right click is curve through points. So select the curve, select the points one by one. See make more points if the curve is very, it's more complex curvature. So you need to add more points. So this way you can also create this kind of curves. Let's turn off the image layer. So this way you can create three different kind of curves. So this is control point cow this is my interpolate cow and right mouse button is a cow through points and fourth one is a handle cow. So if I have turned on this option let's hide these points and you can also move those points. Now if I want to use this handle cow so you need to click on that handle cow and click that point then you need to adjust your handle then again you need to click and adjust your handle again third click then adjust your handle make a fourth click adjust your handle ok so this way you can adjust your tangency after creating new point so this option needs practice so see we can see it open first you need to adjust your tangency means direction then this is my second click then again adjust your tangency with respect to that first point. So, the lower the distance, the lower tangency, the higher the distance you need to means make it more tangent. So, it is little bit tricky and if any anyone is a user of Photoshop, so having this option is very useful for him. So this way we can create multiple cow.",

"text": "Now let's understand what's modified means transform commands how they are working. Suppose I want to split this rectangle with this circle so select this split option and select this rectangle then see it's always you can see your instructions define in this command prompt so it's asking select objects to split which I have selected and now press enter when done. Now select cutting object. So this is my cutting object then enter. Okay, so now you can see that your rectangle is splitted in these two parts. Okay, so this way you can split your object. Suppose, okay, your object should pass through these two points so suppose if I want to split this circle by these two points you can split it so here is the split option okay select the circle then enter and select cutting object so this is my cutting objects so now the circle is converted into two parts okay so this way you can also use these options in future 3D objects. So this way you can split them in two parts. And this is stream option. So if I want to hide these objects, so select these all the objects together. So this is selection window from left to right and from right to left. so what is the difference between selection window? So if I use this option, right to left. So the any objects whose single point even covered in this window will be selected. Got it. And for this left to right selection, the objects which are fully covered means the objects which whole object is covered in this window are selected. So the arc is half see this portion so this is not selected so only the objects which are whole covered inside that window means this window which that will be selected and this is crossing even single point is passing through this crossing window will be selected. So this is very handy. So for this selection select this all the objects and you can see here this is standard option this is hide and that is control plus H for hiding the objects. So let us understand what is frame. So for trimming this all the circles by this vertical circle how to trim it okay so make sure you are into some orthographic view and see this is your cutter and now click on this trim option and select all these circles so this way this is the first way you can select is type in or click here trim option and directly click on that portion which you want to trim. So these are the two different ways to trim the objects. Okay so this way this is the split and this is the trim option. Okay thank you.",

"audio_file": "9%20-%203d%20objects%20and%20Boolean%20operation.wav",
"text": "Okay, so in last session we have seen extruded options. So now let's see how to extrude and how to Boolean means how to subtract and split the objects. So different kind of Boolean operations. So this is very basic techniques. Okay, you can also do basic thing if you want to create street cylinder. So you can make street cylinder by click center first then specify your radius value. So it's a diameter so let's specify 7 and now you need to specify height so this is for the simple kind of cylinders but if you want to merge different cross sections so suppose if I have created one circle having 7 mm diameter and if I need to modify it with a line or something different kind of shape. So there is no readymade commands available. So for this thing I need to first stream this object and make this as a single cross section. So let's join it. So this becomes a single cross section and now I can extrude close planner curve. So here I have extrude curve. So this is the same extrude close planner curve and then I can extrude it. So let's specify 5mm height. Okay. Now suppose I want to bullion it. So let's create one cylinder and I will create cylinder from this midpoint. Okay and understand that this is very basic setting. Let's turn off smart track. Everything which will be created will be automatically set on this sea plane. So this is the sketching plane and everything will be created directly by default on sea plane. So we need if we want to create one circle here. So it's suppose 3.5 and now I'm going to extrude it. So let's make it 10. Okay. Now what my planning is to do, I want to subtract this object from this one. Okay. So we have Boolean operations available here. So these are the Boolean operations. So Boolean difference. So first select bigger one then press enter then select Which objects need to be subtracted so subtract with so select that and again enter so it will subtract that material Okay, now Let's make it undo. Okay, suppose let's create another copy. I will create here. Okay. Okay, keep pressing Alt key and drag this arrow. So this is linear translation arrow. These three arrows are linear translation arrow. If you keep pressing Alt key and click on this arrow you can specify proper value. So suppose that is a tan so it will create a new one with specified distance. Okay so it could be center to center so you can set accordingly by identifying which distance you need to specify from this point to this point either center to center. Okay so by default this objects gumball to this gumball center distance is 10. Okay, how to change gumball we will see it later for right now I need to show you different Boolean operations. Now let's make it split. So select this first object then enter then second object enter. So this will split this object which means which portion is intersected with this object. So, okay. I move this object this automatically moves because of this zachar history I will explain you this thing later for right now I need to explain you this thing let's make it undo. Okay, let me change it individually. So this will change it. So I can say now it will not be dependent. Let's make it a little bit more change. Okay, so let's make it hide for this thing. I need to I need to press this hide of hide button. Okay. Now let's make it Boolean. or what you can do you can turn off this option, delete input no so it will split or intersect and keep both the objects and also it will keep intersection portion as well. Okay so this is as same object which was before and the third option is a split so it will split into original one. So select this one then enter, select this one enter. You can also turn off this option but right now let me keep turn on and now let's see this object is split it with this object. Thank you.",

So for right now, suppose if you want to define some customized key and then for top view, we are using T and type in underscore top. Now let's create another new shortcut key. So P is already given to planner. So let's make a new, let's use Q. Okay. And type in underscore and perspective. Make sure spelling is correct. And now just click okay.

If that can be only possible if you know the exactly name of that tool bar. So, okay, let's start in the top of the Rhino interface. This is the main over. So suppose if you want to turn it on, turn it off. So you can use underscore options. So underscore option is the command and just press enter and you can find below this Rhino option that is the appearance icon where you can turn it off, turn it on, so here is the manual bar. Okay, in advance you can turn it off and on this side, sidebar. So if you type side and you can turn it off and turn it on. Okay, so suppose if I want to reset toolbar, so you must have to restart rhino. So suppose if you give toolbar reset, then you have to, so we will do this later. So at present toolbar reset is the command name. So just remember this thing toolbar reset, then restart rhino after clicking on this command. So at present we are just introducing is interface. Okay, again in the bottom we have a different reports suppose if suppose if you want to maximize any report just double click on that or control n is the key okay control and control and again it will maximize and minimize the report below that we have a objects map or snap options so objects map if it is turned on turn off so if it is turned on, we have all the options are available. So OSNAP is a very important thing. We will see the details later. Below that we have a function key. So the function keys are the heart of the Rhino. This is the very advantage tool. So it will make our task very easy. This is properties toolbar. This is floating toolbar that is properties toolbar. So, of course, if you want, if you have accidentally turned it off, so you can type here properties, it will appear again. Okay. Thank you.",

So let us keep it open here. I can also import it in my Rhino. So let's first convert into JPG image. So just print screen, then print shelf, ctrl V and just save as to eDrive Practice Gallery and N1. Now go to Rhino. Just type in command Teacher Frame and go to eDrive and here Practice CAD and N1 and just go to Front and just go to front and just enter two clicks so you can see all drawing ok suppose if you want to trim it just go another rectangle and use frame command so type in frame command enter select the drawing enter then select the rectangle, then enter Split our requirement Now let and width value So 114 let's type x value first so 114 is the right Enter then it is asking for width see here always read your command command bar. It's asking for width 82 is a width Okay, so I just draw 82 by 114 rectangle it is having 4 chamfer so 10 by 10 is a chamfer. So, let us use chamfer command CHA and just type in distances. So, suppose if you want to change something different value so let us type 12 and the second chamfer distance 12. So, first line will take first distance and second when you click on second line it will take second distance. So, this is my first line this is second line. So, just keep right click press right click it will repeat last command and again click on the both the line one by one. Now, it has one inside circle at distance of 14 and its size is 24 and bottom side its 20 size diameter and it is at height of 10. So let's first create this bottom circle. So let's start lying. Just find middle point. You have to turn on O snap and just turn on middle ok if your mid is clicked then it will only identify the mid point just go inside 10mm value of 10 enter and just click on this direction now go to circle it is for center, so this is my center and it is asking for value, it is asking for radius, so 20 is the diameter, 10 is the radius. Now just create two lines, first, second and now select all of them, this is crossing selection left to right left to right box is a crossing selection Whatever comes inside of that box even small single point of any line it will select all of them then use stream command then just use stream Then I step from the command and select the line and delete Okay, I can use mirror option. so this is a MI enter mirror and just find middle point. Mirror needs mirror plane, so you have to click mirror plane. So it needs two clicks. This is my first click, this is my second click and now select this objects and use print command. Just click on the option. Now the same way we have circle of radius 12 at the height of 14. So, let's create line at the height of 14 and just click on the direction. Now, circle, center, radius of 12, line, find the quadrant, it will only find quadrant if your chord is turned on, it is tick. Just create two lines, it should be passed through the vertical line. Select all the objects frame command and trim all those objects which are not required select the line and delete use mirror option find the mirror plane select the objects and use frame command ok select all of them and control J, Ctrl J is for join, either you can click here, this is join, so this is your now complete object.

"text": "Okay, so now let's see how to create this kind of shape using subdivision options. So in beginning, no cops are common for solid modeling subdivision modeling and surface modeling. So for right now just type in zero enter and type in 10 mm distance and click here. Now if you need to change your color, click here on layer and type in green. Okay, now that is the second line we will take as a polyline so let us jump at one grid line and let us make to the outer side and again back to that same point. So this is my second curve. We will move up this line at 30 mm distance. We need another copy of this line at 20 mm so keep pressing Alt key and click here as a 20 so this line will go at 20 mm height okay now I want to change this rectangle from this point to this point so select the line turn on this edit points and select these points now click on this option see I have selected these all the points now click here and type in 6 mm distance so it all the points will be move at this distance. Now, we need to use only subdivision options. So, here is the sub D loft. So, what will loft do? It will connect all the cross sections. So, we need to select this cross sections sequence wise and we will need to use this corners option now turn on this shaded option you can change the style see this style is depend on a micross section so if you need to adjust your shape segments so you can adjust them using 15 multiple options now division between shapes so these are the shapes 1 2 and 3 so if need to add divisions, so I can also add new divisions. So, it will add 6 divisions in between these cross sections. So, it will make more smooth mesh. Now, press ok, select this option and type in mirror option, select this point to this point. So, this way we can create this kind of beautiful shape. Now, select them and type in control j. So will join them once the join option is done let's select all of them and move it apart. Okay now create one circle type in zero enter and specify radius diameter is a 30 so 30 is your diameter now select it circle and type in division command sorry divide command now after this option appears you need to press enter and then after you need to click turn on this option split yes and number of segments here is the six now click done so see you can see here the circle has been divided into multiple sections okay now see I need to set this line, see here is the line, oops where is where it is gone, okay it is not there is no line so we will create a new line of 10 mm so from this point to this point, okay. Now I want to apply this design on this particular segment so select first option, now type in flow along cow, select your baseline and this is my target cow line. in the it's not properly matched. So let's make it undo. We need to flow it again. So make it again undo. Okay, again, I will select this option, type in flow. Okay, I need to turn on this stretch option. If the stretch option is a turn off, see it will not match ends perfectly. So for right now, keep turn on the stretch. Now it is asking for the base code. This is my base code and this is my target code. Let's move it here. Okay. So select your bottom code. See, it should match it's start and end points perfectly. Okay, now this way you can select the top means this segment, this portion, this surface. Okay, now you can apply any polar option. Type in zero enter and the more of segments are six. So, see its ends are perfectly matching. So, the stretch option makes the game be, game winner. So, select the upper portion, now go to front view and type in meter, zero enter and make a straight meter line, select the bottom portions and type in join command. So, all the surfaces will become a single unit single model. Now, we will use cage edit. So, here is the cage edit option. Select the bounding box, world, type in all the four options. Okay, four is fine. And now global, G enter. Select the both options, scale it out of sight. As per your requirement, you can also select the top portion and bottom portion. We also move them inside. So here is the inner side option. So let's first click outer side select the top portion select the bottom and move it inner side. So this way you can make your design beautiful okay and now if you want to make a 3D print so go to render. Okay now hide these both the sorry hide these extra objects and move them into another layer hide them, okay also select this circle hide them, okay now use offset sub D. So, offset sub D and now specify your distance C, your surfaces have very small segments. So, you need to specify very proper distance otherwise you need to create extra circle inside and then you can join them for right now I am just going to use a 0.25 outer side and just done. So this object become solid. So you can now 3D print this object. Okay. Thank you.",
