Run Interference Detection Example (VB.NET)

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.
