Check Interference using IAssemblyDoc::ToolsCheckInterference2 Example (VBA)

This example shows how to check an assembly for interference using IAssemblyDoc::ToolsCheckInterference2.

'----------------------------------------------------------
' Preconditions:
' 1. Open a fully resolved assembly that contains at least
'    two interfering components.
' 2. Select at least two interfering components.
' 3. Open the Immediate window.
'
' Postconditions:
' 1. Selects the interfering faces.
' 2. Examine the graphics area and Immediate window, then
'    press F5.
' 3. Selects the interfering components.
' 4. Examine the graphics area and Immediate window, then
'    press F5.
