Load an AutoLISP File

AutoLISP (LSP or MNL) files contain programs that add custom commands and functions which can be used as part of the user interface. You can load AutoLISP files into a CUIx file using the Customize tab of the Customize User Interface (CUI) Editor.

For more information about using AutoLISP, see AutoLISP and Visual LISP.

TipMNL files with the same name and location as your main, enterprise, or partial CUIx files are loaded automatically. These files cannot be unloaded once loaded into AutoCAD.
