(getvar "env.acadreleasename") $(getvar, env.acadreleasename) 3. Visual LISP (VLISP) (vl-load-com) (vla-get-SystemVariables (vla-get-ActiveDocument (vlax-get-acad-object))) 4. Command Line (Quick Check) Simply type:

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. 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. (getvar "env

In the world of AutoCAD and its衍生品 (derivatives) like AutoCAD Civil 3D, AutoCAD Architecture, and Mechanical, system variables and environment parameters form the backbone of automation, customization, and debugging. Among these, env.acadreleasename is a powerful, read-only system variable that provides developers, administrators, and power users with precise information about the running AutoCAD environment.

(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.

Unlike the more common ACADVER (which returns a more cryptic, build-oriented code like "24.3s (LMS Tech)" ), env.acadreleasename returns a human-readable, user-friendly product name.
