Get Guide Curves in Sweep Feature Example (C#)

This example shows how to get the guide curves in a sweep feature.

//----------------------------------------
// Preconditions: 
// 1. Verify that the specified part document 
//    template exists.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Creates a new part document.
// 2. Creates a sweep feature.
// 3. Prints to the Immediate window the
//    number of guide curves in the sweep
//    feature.
// 4. Accesses the guide curves in the sweep feature.
// 5. Prints to the Immediate window the feature types
//    of the guide curves.
// 6. Releases access to the sweep feature.
// 7. Examine the Immediate window.
