Insert Protrusion Blend Example (VBA)

This example shows how to create a loft using profiles, guide curves, and a centerline.

'---------------------------------------------------------------
' Preconditions: Verify that the specified part template exists.
'
' Postconditions:
' 1. Creates a new part.
' 2. Creates a profile sketch.
' 3. Creates a reference plane and another profile sketch on that
'    reference plane.
' 4. Creates five curves: four guide curves and one centerline.
' 5. Selects the profile sketches, four guide curves, and the 
'    centerline.
' 6. Creates a loft feature.
' 7. Examine the FeatureManager design tree and graphics area.
