Subject: Understanding menu compatibility

CUI format menu files are created by newer versions of AutoCAD. MNU format files are menu files created by all AutoCAD releases, and MNS format files are included in AutoCAD Releases 13, 14, and 2000. CADdirect reads all file formats, even when menu macros include AutoLISP code. This feature allows you to continue using your existing AutoCAD menus.

CADdirect supports all sections of CUI format files required for customization.

For MNU and MNS format file compatibility, see the following table.
