Create New Part from Existing Part Using Temporary Body Example (C#)

This example shows how to delete faces from a temporary body and how to create a new part using that temporary body.

//---------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\tutorial\toolbox\braceright.sldprt.
// 2. Verify that the specified part template exists..
//
// Postconditions:
// 1. Creates a new part; the new part has same body as original part
//    but with selected faces deleted.
// 2. Close the new part without saving it.
// 3. Close braceright.sldprt without saving it.
