Create Derived Pattern Feature Example (VB.NET)

This example shows how to create a derived pattern feature.

'--------------------------------------------------------------------
' Preconditions:
' 1. Verify that the assembly to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the assembly.
' 2. Creates a derived pattern feature.
' 3. Gets the type and name of the pattern feature used for
'    the derived pattern feature.
' 4. Changes the position of the pattern instance used as the seed
'    feature in the derived pattern feature.
' 5. Examine the FeatureManager design tree, Immediate window, and
'    graphics area.
'
' NOTE: Because the assembly is used elsewhere, do not save changes.
