Simplest way is as alanjt suggested. Other method would be to add a
(load "LispFilename") in the ACADDOC.LSP file or the MNL file of your CUI menu.
If you only want to load it once, use the APPLOAD and simply select it & click load ... or type
(load "LispFilename") at the command prompt.
If you want it to only load once you enter one of the commands inside, add the following to the ACADDOC.LSP or MNL file:
Code:
(autoload "LispFilename" '("1stCommand" "2ndCommand" ....))
If you go the ACADDOC route, check if there's already an ACADDOC.LSP ... type
(findfile "ACADDOC.LSP") at the command line & see where it's stored. If there's none, then create one using the VLISP command or a text editor like Notepad in one of the support folders. Never use the ACADDOC20##.LSP, that one's meant for the guys at ADesk and may become overwritten by an update.
