Get Surface-finish Image Path and File Name Example (C#)

This example shows how to set and get the path and file name of the image used for an appearance's surface finish.

//----------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified model document exists.
// 2. Verify that the specified materials and surface-finish image
//    files exist.
// 3. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified model document.
// 2. Applies the specified appearance and surface finish to the model.
// 3. Gets the file names of the first appearance and surface finish
//    applied to the model.
// 4. Examine the graphics area and the Immediate window.
//
// NOTE: Because the model is used elsewhere, do not save changes.
