Run Interference Detection Example (VB.NET)

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

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open:

' <SolidWorks_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 in SolidWorks tutorials,

' do not save any changes to it.
