Offset Sketch Example (C#)

This example shows how to offset a sketch.

//----------------------------------------------------------------------------
// Preconditions: Verify that the specified part template exists.
//
// Postconditions:
// 1. Creates a new part.
// 2. Sketches a line.
// 3. Offsets the line 2.54 mm in both directions.
// 4. Examine the graphics area.
