Detect Interferences Using a Transform Example (VB.NET)

This example shows how to specify a transform to detect interferences.

'----------------------------------------------------------------------------
' Preconditions:
' 1. Open install_dir\samples\tutorial\api\InterferenceAssem.sldasm.
' 2. Uncomment one of the userOpt assignments.
'
' Postconditions:
' 1. When the macro stops, observe the position of the components in the
'    graphics area.
' 2. Press F5 to continue.
' 3. Inspect the Immediate Window for interfering components.
'
' NOTE: Because the model is used elsewhere,
' do not save changes when closing it.
