Run Interference Detection Example (C#)

This example shows how to run interference detection and observe the interferences in an assembly.

//---------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\samples\tutorial\advdrawings\bowl and chute.sldasm.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the Interference Detection pane.
// 2. Gets interferences.
// 3. Gets interfering components and transforms.
// 4. Gets interference information.
// 5. In the Results list on the Interference Detection pane,
//    click on each interference and observe it in the graphics area (red).
// 6. To close the Interference Detection pane, right-click the graphics area
//    and select Cancel.
// 7. Inspect the Immediate window.
//
// NOTE: Because the assembly is used elsewhere, do not save changes.
