Traverse Annotations Example (C#)

This example shows how to get display dimension annotations.

//-----------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part document exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part document and selects
//    a sketch containing multiple dimensions.
// 2. Iterates the display dimensions and gets 
//    each display dimension annotation and its position.
// 3. Moves each display dimension annotation 100mm to
//    the right.
// 4. Examine the graphics area and Immediate window.
//
// NOTE: Because the part document is used elsewhere, do not
// save changes.
