||This task shows you how to delete
useless or un-referenced elements,
i.e. elements not participating in the creation of other geometrical
elements. The command deletes all unreferenced elements of the part. If you
do not want all elements to be deleted, you have to specify it.
Select Tools > Delete Useless Elements
The Delete Useless Elements dialog box appears.
It lists all the geometrical elements, datum or not, that are present in
the document or in other documents when working in context: in a
CATProduct document referencing CATPart documents.
Elements used by a Part Design feature have the Keep, used by solid
status meaning they cannot be deleted. In our scenario, three elements
are mentioned with the Delete status.
If you do not wish to delete all possible elements,
right-click the element of interest and select Keep. For instance, apply this
contextual command to
The list of un-referenced elements is automatically updated, indicating a

status is "Keep, propagate".
In the bottom left corner of the dialog box, the global
status is also updated.
Click OK to confirm the deletion of all
elements listed with the Delete status.

Bodies, whether Geometrical Sets, Ordered Geometrical
Sets or PartBodies located directly below the main Part are not displayed
in the list, as when creating a new document, they are necessarily empty
of geometric elements, and it does not make sense to delete them.
