Only Show Selected Components Example (VBA)

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

 

'----------------------------------------------------

'

' Preconditions:

'       (1) Assembly is open.

'       (2) One or more components are selected either in the

'           graphics area or in the FeatureManager design tree.

'

' Postconditions: All components, except selected components, are hidden.

'

' NOTES:

'       (1) If a subassembly is selected, all child components (parts

'           and sub-subassemblies, are shown.

'       (2) If a sub-subassembly is selected, all parents are recursively

'           shown to the top-level assembly.
