Delete a Smart Feature Example (C#)

This example shows how to delete a feature from a Smart Component.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Open public_documents\tutorial\api\holecube.sldprt.
// 2. Expand the Smart Feature and Features folders to verify that
//    Features contains two extrusion features.
//
// Postconditions:
// 1. Deletes one extrusion feature from the Features folder.
// 2. Expand the Smart Feature and Features folders to verify that
//    Features contains one extrusion feature.
//
// NOTE: Because the model is used elsewhere, do not save changes.
