Create Extrude Feature Using Sketch Contours Example (C#)

This example shows how to create an extrude feature using sketch contours.

//--------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part template exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens a new part document.
// 2. Creates a sketch containing sketch contours.
// 3. Creates a boss extrude feature using the sketch of sketch
//    contours.
// 4. Selects the boss extrude feature and accesses
//    its data.
// 5. Gets the sketch contours.
// 6. Get whether each sketch contour is open or closed.
// 7. Examine the FeatureManager design tree, graphics area, and
//    the Immediate window.
