Create Shell Feature Example (VBA)

This example shows how to create a shell feature.

'---------------------------------------------------------------------------
' Preconditions:
' 1. Verify that the specified model document exists.
' 2. Open an Immediate window.
'
' Postconditions:
' 1. Selects a face to remove from the model to create the shell.
' 2. Creates Shell1.
' 3. Inspect the Immediate window, graphics area, and
'    FeatureManager design tree.
'
' NOTE: Because the model is used elsewhere, do not save changes.
