Get Data for Surface-flatten Feature Example (VBA)

This example shows how to insert a surface-flatten feature and get its data.

'-------------------------------------------------------
' Preconditions:
' 1. Verify that the part to open exists.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Opens the part.
' 2. Inserts a surface-flatten feature.
' 3. Gets surface-flatten feature data.
' 4. Examine the graphics area and FeatureManager design
'    tree.
'
' NOTE: Because this part is used elsewhere, do not save
' changes.
