Create a Thread Feature Example (C#)

This example shows how to create and edit a thread feature.

//---------------------------------------------------------------------------- 
// Preconditions: 
// 1. Open:
//    public_documents\samples\tutorial\api\holecube.sldprt
// 2. Open an Immediate window.
// 
// Postconditions: 
// 1. Creates Thread1.
// 2. Modifies the start angle and overrides the pitch of Thread1.
// 3. Inspect the Immediate window.
//
// NOTE: Because the model is used elsewhere, do not save changes.
