Create Extrude Feature Using Sketch Contours Example (VBA)

This example shows how to create an extrude feature using sketch contours.

'--------------------------------------------------------------
' Preconditions:
' 1. Verify that the specified part template exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens a new part document.
' 2. Creates a sketch containing sketch contours.
' 3. Creates a boss extrude feature using the sketch of sketch
'    contours.
' 4. Selects the boss extrude feature and accesses
'    its data.
' 5. Gets the sketch contours.
' 6. Get whether each sketch contour is open or closed.
' 7. Examine the FeatureManager design tree, graphics area, and
'    the Immediate window.
