Only Show Selected Components Example (VBA)

This example shows how to only show the selected components in an assembly.

'----------------------------------------------------
' Preconditions:
' 1. Open an assembly.
' 2. Select one or more components.
' 3. Open the Immediate window.
'
' Postconditions:
' 1. Hides all components except the selected components.
' 2. Examine the Immediate window, graphics area, and the
'    FeatureManager design tree.
'
' NOTES:
' * If a subassembly is selected, then all child components
'   (parts and sub-subassemblies) are shown.
' * If a sub-subassembly is selected, all parents are recursively
'   shown at the top-level assembly.
