Get Guide Curves in Sweep Feature Example (VBA)

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

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