Insert Free Point Curve Feature Example (C#)

This example shows how to insert a free point curve feature.

// Preconditions:
// 1. Verify that the specified part template exists.
// 2. Create c:\temp, if this folder does not exist.
// 3. Open the Immediate window.
// Postconditions:
// 1. Creates a new part document.
// 2. Inserts a free point curve feature.
// 3. Gets some free point curve feature data.
// 4. Saves the free point curve feature's points to a file.
// 5. Examine the graphics area, FeatureManager design tree,
//    Immediate window, and c:\temp.
