AutoCAD System Variable (SYSVAR) Reference: 2000 → 2026

Critical scripting variables • Read-only values • Version history • SETVAR usage in Hurricane batch scripts


How to use this table: Hurricane sets system variables using the SETVAR command (e.g. SETVAR FILEDIA 0) or by typing the variable name directly at the command prompt. Variables marked KEY must be set at the start of any serious batch script — skipping them causes dialogs or prompts to pause unattended runs. Variables marked SET are useful to configure in scripts. Variables marked READ are read-only and can be queried in AutoLISP with (getvar "VARNAME"). Use the filter buttons or the search box to find what you need.
