Run Interference Detection Example (VBA)

This example shows how to run interference detection on an assembly.

' Preconditions:
' 1. Open install_dir\samples\tutorial\advdrawings\bowl and chute.sldasm.
' 2. Open an Immediate window.
' Postconditions: Inspect the Immediate window for interference information.
' NOTE: Because the assembly is used elsewhere, do not save changes to it.
