Create and Access Curve-driven Pattern Feature Example (C#)

This example shows how to create a curve-driven pattern feature and access its data.

//--------------------------------------------------------------
// Preconditions:
// 1. Verify that the specified part document to open exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified part document.
// 2. Creates a cut extrude feature.
// 3. Creates a curve-driven pattern feature using the
//    the cut extrude feature.
// 4. Gets curve-driven pattern feature data.
// 5. Examine the FeatureManager design tree, graphics area,
//    and Immediate window.
//
// NOTE: Because the part is used elsewhere, do not save changes.
