Create Split Feature Example (C#)

This example shows how to create a Split feature.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open a part document that contains a body that is bisected by the 
//    Top Plane.
// 2. Verify that c:\temp exists.
// 3. Open an Immediate window.
//
// Postconditions:
// 1. Creates Split1.
// 2. Saves a split body to c:\temp\Body1.sldprt.
// 3. Inspect the Immediate window, FeatureManager design tree, graphics area,
//    and c:\temp.
