Scripts

The Script Manager (Ctrl+5) lets you write and execute AutoCAD scripts across multiple DWG files in batch, with a dedicated terminal per file.

The page is split into the file list, the script editor, and the terminal panel to the right of the editor. All three panes can be resized by dragging the dividers between them.

Script Editor

The editor supports two script formats:

• .SCR: AutoCAD command scripts (plain command sequences)
• .LSP: AutoLISP programs

It highlights LISP syntax and shows whitespace markers, which matters in command scripts where a blank line or trailing space is a command input.

Lines that start with ;; (at the beginning of the line) are treated as comments and stripped before execution.

Script Menu

The Script menu above the editor contains:

• Open: Load a .scr or .lsp file into the editor.
• Save / Save as: Write the editor content back to a file (Save is available once the script has a file path).
• History: Reopen a recently used script file, or clear the history.

Run Environments

Scripts can run in three environments: CAD (new visible AutoCAD instance), CAD attach (an already running AutoCAD), or Background (parallel headless processes). Select one from the eye-icon menu in the toolbar; the default is Background and can be changed in Settings (Ctrl+6) under Script manager.

See Run Environments for how each mode behaves, including how script output streaming and prompt answering differ per environment.

Running Scripts

The Run button starts the script on all files; use its dropdown to instead run only on the files selected in the file list. Each file gets its own terminal; select a single file in the file list to view its output.

Pressing Stop behaves differently per environment:

• CAD / CAD attach: the file currently running finishes, remaining files are skipped, and AutoCAD shuts down cleanly.
• Background: running workers are stopped immediately and queued files are dropped.

Example Scripts

Purge and Save (.SCR)

This command script purges all unused items and saves the drawing:

-PURGE
ALL

N
QSAVE

Simple AutoLISP (.LSP)

This AutoLISP snippet prints the drawing filename to the command line:

;; Print current filename
(princ (strcat "\nFile: " (getvar "DWGNAME")))
(princ)
