Detect Interferences Using a Transform Example (C#)

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.
