Create, Unlink, and Purge Display States in Part Example (C#)

This example shows how to create, unlink, and purge display states in a part document.

//---------------------------------------------
// Preconditions:
// 1. Open install_dir\samples\tutorial\multibody\multi-inter.sldprt,
//    whose Default configuration has two display states:
//    * PhotoWorks Display
//    * Display State 1
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Creates and unlinks Display State 2.
// 2. Attempts to purge any display states identical to
//    Display State 2.
// 3. Closes the part document without saving any changes.
// 4. Examine the Immediate window.
