Update Graphics Area After Changing Render Options Example (C#)

This example shows how to update the graphics area after changing the ray-trace render engine's options.

//----------------------------------------------------------------------------
// Preconditions:
// 1. Verify that:
//    * specified part exists.
//    * PhotoView 360 add-in is loaded in SOLIDWORKS.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. If prompted to use perspective views in rendering, click 
//    Continue without camera or perspective and OK.
// 2. Changes the specified render options and updates the graphics area.
// 3. Examine the graphics area and Immediate window.
//
// NOTE: Because the part is used elsewhere, do not save changes.
