Change Angle to Supplementary Angle Example (C#)

This example shows how to change the angle in an angular dimension to its supplementary angle.

//-----------------------------------------------------------
// Preconditions: Verify that the drawing exists.
//
// Postconditions:
// 1. Opens the drawing.
// 2. Selects the angular dimension.
// 3. Changes the angle to its supplementary angle.
// 4. Examine the graphics area.
//
// NOTE: Because the drawing is used elsewhere, do not save
// changes.
