Command.vb
It contains the class Command which implements interface IExternalCommand and the generating process of the section view across the mid point of a linear element. It also contains a class CreateDraftingView to create a drafting view.

XYZMath.cs
It gives operations about point and vector presented by XYZ structure.

Description: 
This sample provides following functionalities.
-       
Retrieve the selected linear element.
-       
Generate a BoundingBoxXYZ instance which will be used in NewViewSection() method
-       
set its Max and Min property
-       
Generate a Transform instance as the Transform property of BoundingBoxXYZ which defines the Origin and the directions (including RightDirection, UpDirection and ViewDirection) of the created view
-       
Create the section view using the BoundingBoxXYZ.

Instructions: 
1.      
Open Revit Structure.
2.      
Draw a linear element (wall, structural floor or structural beam).
3.      
Select the element and execute the external command Command.
Or
1.      
Open Revit Structure.
2.      
Execute the external command CreateDraftingView.
