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.
