In an assembly, it is possible to create some groups of parts to ease their selection.

If you want to create a group:

1. Go to the "DMU Navigator" workbench (Start ➞ Digital Mockup ➞ DMU Navigator).
2. Click "Group".
3. Select all the "objects" that need to be grouped, from the Catia three or directly in the 3D model.
4. Click "Ok".

In the link under, you can see step by step how to do it.

If you want to use or to modify the group, you can easily find more detailed explanation in the document below.
