Run Interference Detection Example (C#)

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.

// 3. Rename the namespace of this macro to match the name of your C# project.
//
// Postconditions: Inspect the Immediate Window for interference information.
//

// NOTE: Because the assembly is used in SolidWorks tutorials,

// do not save any changes to it.
