Get and Fill Gaps in Body Example (VBA)

This example shows how to get and fill the gaps in a body.

'---------------------------------------------------------------
' Preconditions:
' 1. Open a model document that contains at least one body
'    with one or more gaps.
' 2. Open the Immediate window.
'
' Postconditions:
' 1. Identifies the number of gaps in each
'    body and fills each gap with a fill-surface
'    feature.
' 2. Examine the Immediate window and the FeatureManager
'    design tree.
