Add Decal Example (C#)

This example shows how to add a decal to a selected face on a part.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part document to open exists.
// 2. Verify that the specified decal files exist.
// 3. Select Tools > Add-ins > PhotoView 360.
// 4. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part document.
// 2. Selects the face where to apply a decal.
// 3. Applies a decal to the selected face.
// 4. Gets the properties of the decal and prints them
//    to the Immediate window.
// 5. Examine the graphics area and the Immediate window.
//
// NOTE: Because the part is used elsewhere, do not save changes.
