Selection Lists Example (VBA)

If you specify a positive, non-0 mark for an object (e.g., 1 or 2 or 3, etc.) and then specify to select only the objects with that mark, then the resulting selection list contains only those objects with that mark. This selection list is independent of a selection list created by selecting all of the objects.

' Preconditions:
' 1. Verify that the specified part document to open exists.
' 2. Examine the Immediate window.
' Postconditions:

' 2. Selects all of the extrude features and marks Base-Extrude
'    and Boss-Extrude5 with a value of 8.
' 3. Gets the number of marked selections and total number of
'    selections.
' 4. Examine the Immediate window.
