| # Draw a closed profile with a 4-point fitted spline |
|
|
| Using only Autodesk Fusion's visible user interface, complete the sketch task below. Work in the root component and use millimetres. Do not use scripts, add-ins, the API, or any external CAD program. |
|
|
| ## Starting state |
|
|
| The supplied design is a clean parametric design in millimetres. It contains only the root component and Origin; it has no sketches, components, features, construction planes, or bodies. |
|
|
| ## Required result |
|
|
| Create exactly one new 2D sketch on the XZ origin plane. Select that plane directly from the Origin folder when Fusion asks for the sketch plane. |
|
|
| All coordinates below are local sketch coordinates in millimetres. X and Y refer to the axes displayed while editing the sketch, viewed normal to the selected sketch plane. They describe the required final geometry: establish them with dimensions and geometric constraints rather than relying on visual grid placement. Unless a requirement names a particular operation or constraint, any visible-UI construction sequence that produces the same final geometry is acceptable. |
|
|
| 1. Draw a regular, non-construction fitted spline through these fit points in order: (-25, 0) mm, (-8.333333, 24) mm, (8.333333, 24) mm, (25, 0) mm. Use Fusion's default fitted-spline shape and do not add tangent handles. |
| 2. Draw a regular, non-construction line from (25, 0) mm to (4, -24) mm. |
| 3. Draw a regular, non-construction line from (4, -24) mm to (-25, 0) mm. |
|
|
| ## Constraints and design intent |
|
|
| - Create exactly one fitted spline by placing these 4 fit points once and in order: (-25, 0) mm, (-8.333333, 24) mm, (8.333333, 24) mm, (25, 0) mm. |
| - From the final spline point draw one line to (4, -24) mm and a second line back to the first spline point. |
| - Do not edit tangent handles, convert the spline type, insert fit points, or drag the generated curve after placement. |
| - Make the three curve junctions coincident so there is exactly one closed profile. |
| - Full constraint is not required for this task; do not alter the requested geometry merely to force a fully-constrained status. |
|
|
| ## Completion requirements |
|
|
| - The final design must contain exactly 1 sketch and 0 solid or surface bodies. |
| - The requested geometry must produce exactly 1 closed sketch profile. |
| - Use regular sketch geometry unless an entity is explicitly described as construction geometry. |
| - Do not add extra sketches, curves, points, projected geometry, text, components, features, or bodies. |
| - Finish the sketch and leave the completed design open in Fusion. |
|
|
| Recommended interaction budget: 95 steps and 300 seconds. |
|
|
| Do not use Save or Save As. Do not open or import any external CAD file, including another task seed or answer. The environment exports the open design automatically; use the finish action when the task is complete. |
