CUIX
AutoCAD's customization file — a zipped XML bundle of menus, ribbon tabs, toolbars, keyboard shortcuts, and the LISP/MNL files they reference.
A .cuix file is AutoCAD's modern customization package: a zip that contains CUI XML defining ribbon tabs, panels, menus, toolbars, palettes, and keyboard shortcuts, plus referenced image and MNL files. Load a CUIX with the CUILOAD command or by dragging it into AutoCAD. Most commercial plugins ship a CUIX so the user immediately sees ribbon buttons for the new commands, instead of having to type them.
