Get Guide Curves in Loft Feature Example (C#)

This example shows how to get the guide curves in a loft 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 loft feature.
// 3. Prints to the Immediate window
//    the feature type and feature name of the loft 
//    feature.
// 4. Accesses the guide curves in the loft feature.
// 5. Prints to the Immediate window whether the
//    loft is a boss feature, the number guide
//    curves in the loft, and the feature types of 
//    the guide curves.
// 6. Releases access to the loft feature.
// 7. Examine the Immediate window.
