Insert MidSurface in Component Example (VBA)

This example shows how to insert a midsurface feature in a component.

' Preconditions:
' 1. Open an assembly that contains at least one component
'    that contains a solid body.
' 2. Open the Immediate window.
' Postconditions:
' 1. Inserts a midsurface feature in the component.
' 2. Gets the number of faces in the midsurface feature.
' 3. Examine the Immediate window.
' 4. Expand the component in the FeatureManager design tree
'    in which the midsurface feature was inserted to
'    verify step 1.
