Delete Blended Faces Example (C#)

This example shows how to delete blended faces.  

NOTE:  You can only delete blended faces from a temporary body.

//--------------------------------------------------
// Preconditions:
// 1. Open a part that contains one solid body
//    and at least one blended (fillet) face.
// 2. Select a blended face.
//
// Postconditions:
// 1. Creates a new part, which has the same body as
//    the original part, but the selected blended
//    face is removed.
// 2. Examine the graphics area.
//
// NOTE: It might not be possible to remove the
// selected blended face. If it's not removed, then
// the new body is the same as the original
// body.
