You can attach an entire drawing to the current drawing as an external reference
(xref). With xrefs, changes in the referenced drawing are reflected in the
current drawing. Attached xrefs are linked to, but not actually inserted in,
another drawing. Therefore, with xrefs you can build drawings without
significantly increasing the drawing file size.
The MenuGroups collection contains the menu groups that are
loaded in the current AutoCAD session. These menu groups contain all the menus
that are available to the AutoCAD session, some or all of which may be displayed
on the AutoCAD menu bar. In addition to the menus, the menu groups also contain
all the toolbars that are available to the current AutoCAD session. Menu groups
may also represent tile menus, screen menus, or tablet menus.
