Env.acadreleasename Guide

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.

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.

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.

(setvar "modemacro" "Running $(getvar, env.acadreleasename) - Ready") It is important not to confuse these two: Unlike the more common ACADVER (which returns a

(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. Next time you fire up AutoCAD and need
