Set Radial Dimension Leader Example (C#)

This example shows how to attach a radial dimension leader to an arc extension line.

//---------------------------------------------------------------
// Preconditions: 
// 1. Verify that the part to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the part.
// 2. Edits the sketch and creates a fillet.
// 3. Attaches the radial dimension leader to the arc extension
//    line.
// 4. Gets whether the radial dimension leader is attached to
//    the arc extension line.
// 5. Examine the graphics area, then press F5.
// 6. Exits the sketch.
// 7. Examine the Immediate window.
//
// NOTE: Because the part is used elsewhere, do not save changes.
