Add Reference Dimension Example (C#)

This example shows how to add a reference dimension to a model in a drawing.

//---------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified drawing document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified drawing document.
// 2. Activates a drawing view, selects an edge on the model, and
//    creates a dimension.
// 3. Prints to the Immediate window whether the dimension
//    is a reference dimension.
// 4. Examine the Immediate window.
//
// NOTE: Because the drawing document is used elsewhere, do not
// save any changes.
