Create and Access Curve-driven Pattern Feature Example (VB.NET)

This example shows how to create a curve-driven pattern feature and access its data.

'--------------------------------------------------------------
' Preconditions:
' 1. Verify that the specified part to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the specified part document.
' 2. Creates a cut extrude feature.
' 3. Creates a curve-driven pattern feature using the
'    the cut extrude feature.
' 4. Gets curve-driven pattern feature data.
' 5. Examine the FeatureManager design tree, graphics area,
'    and Immediate window.
'
' NOTE: Because the part is used elsewhere, do not save changes.
