Get Corresponding Entities Between Parts and Drawing Views Example (C#)

This example shows how to get corresponding entities or objects between a part and its drawing.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Ensure that the specified part and drawing exist.
// 2. Open the Immediate window.
// 3. Uncomment the subroutine you want to run in Main().
// 4. At the pause, select a face, edge, vertex, feature, annotation,
//    or sketch segment.
// 5. Press F5.
//
// Postconditions:
// 1. Inspect the Immediate window.
// 2. If a corresponding face, edge, or vertex is found, it is selected in the
//    underlying part or drawing.
//
// NOTE: Because the models are used elsewhere, do not save changes.
