Named Selection Sets
You can also edit the contents of named sets from the Named Selection Sets dialog.
As you model and create a scene, you’re likely to rearrange the objects making up your named selection sets. If you do, you’ll need to edit the contents of those sets.
To assign a name to a selection set:
Select one or more objects or sub-objects using any combination of selection methods.
Click in the Named Selection field on the main toolbar.
Enter a name for your set. The name can contain any standard ASCII characters, including letters, numerals, symbols, punctuation, and spaces.

To retrieve a named selection set:
In the Named Selection field, click the arrow.
