While not a command you type daily, understanding env.acadreleasename is crucial for writing robust LISP routines, creating fail-safe scripts, and managing multi-version deployments. env.acadreleasename is a system variable that returns a string (text value) containing the marketing name of the currently running AutoCAD release.
(setvar "modemacro" "Running $(getvar, env.acadreleasename) - Ready") It is important not to confuse these two: env.acadreleasename
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") . While not a command you type daily, understanding env
| Feature | env.acadreleasename | ACADVER | |---------|------------------------|-----------| | | "AutoCAD 2024" | "R24.3" | | Readability | High (user-friendly) | Low (developer-oriented) | | Includes LT/Full | Yes | No | | Includes service pack | Sometimes (e.g., 2022.1.2) | Rarely | | Best for | UI messages, user feedback | Exact API/COM compatibility checks | | Feature | env
(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.
(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.
( 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.
