Change Texture on Face in Specified Configuration Example (C#)

This example shows how to change the texture on the selected face in the specified configuration.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Ensure the specified textures exist.
// 2. Open a part or assembly with a Default configuration.
// 3. Select a face.
// 4. Open an Immediate window.
//
// Postconditions:
// 1. Applies texture to the selected face.
// 2. Inspect the Immediate window and the model.
