Get Selected Faces on Processed Body Example (C#)

This example shows how to get the selected faces on a processed body.

//------------------------------------------------
// Preconditions:
// 1. Verify that the specified part document template
//    and part exist.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part.
// 2. Creates a new part with an imported body
//    from the processed body of the original part.
// 3. Gets the body in the new part and selects
//    multiple faces on that body.
// 4. Examine the Immediate window.
//
// NOTE: Because the part is used elsewhere, do not
// save changes.
