If your drawing scale requires conversion (e.g., converting mm2m m squared m2m squared ), divide the total area in the LISP code. 6. Alternatives to LISP (CAD Tools)

The Lisp does this in : TOTAREA (or similar). You select 50 objects, press Enter, and it instantly tells you: Total Area = 2750.00 Sq. Ft.
: Sum dozens of separate enclaves or rooms in two clicks instead of hours of manual addition. If your drawing scale requires conversion (e
Disclaimer: Please test this LISP routine on a copy of your drawing to ensure it fits your specific CAD standards.

It is one of the highest ROI (Return on Investment) tools you can add to your AutoCAD setup—considering it costs nothing but saves hours. Your primary (e
If you are looking for a specific Lisp to use, I highly recommend checking out Lee Mac’s "Area Label" Lisp or Totten Lisp . These are industry standards that offer robust features like auto-labeling and field integration.
;; Step 1: Create a selection set (setq ss (ssget '((0 . "LWPOLYLINE,CIRCLE,ELLIPSE,SPLINE,REGION,HATCH"))))
:Divide the output by 1,000,000. (setq total (+ total (/ area 1000000.0))) Use code with caution.
This post shows a compact, reliable AutoLISP routine to calculate the total area of selected closed polylines and closed circle/ellipse-like objects in an AutoCAD drawing, plus instructions for loading and using it.
For users needing precision and support for modern AutoCAD features, Total Length & Area program is a standard in the industry. Lee Mac Programming
