(setq acadVer (getenv "acadreleasename")) (cond ((wcmatch acadVer " 2024 ") (load "features-2024.lsp")) ((wcmatch acadVer " 2023 ") (load "features-2023.lsp")) ((wcmatch acadVer " 2022 ") (load "features-2022.lsp")) (t (alert "Unsupported AutoCAD version!")) ) When deploying custom CUIx (menu) files or ARX applications, you can verify that the user is running a compatible release before loading critical extensions. 3. Debugging and Logging In enterprise environments, when a user reports an error, your error handler can log env.acadreleasename to help isolate whether the issue is version-specific.
Next time you fire up AutoCAD and need to know exactly what release you are on—without digging through the About box—just reach for (getenv "acadreleasename") . env.acadreleasename
( getenv "acadreleasename" ) inside AutoCAD’s command line and press Enter. 1. Version-Specific Scripts If you maintain a library of LISP routines that behave differently across AutoCAD versions (e.g., different command syntax or function availability), you can use env.acadreleasename to branch logic. Next time you fire up AutoCAD and need
(setvar "modemacro" "Running $(getvar, env.acadreleasename) - Ready") It is important not to confuse these two: Version-Specific Scripts If you maintain a library of
(defun log-error (errmsg) (setq logfile (open "C:\Temp\cad_error.log" "a")) (write-line (strcat "Date: " (rtos (getvar "date") 2 8) " | AutoCAD: " (getenv "acadreleasename") " | Error: " errmsg) logfile) (close logfile) ) You can include env.acadreleasename in your MODEMACRO (status line display) to always remind users (or yourself) which release is active, useful when running multiple versions side-by-side.
