Total: Area Autocad Lisp

Fortunately, AutoLISP (AutoCAD’s built-in scripting language) offers a seamless solution. By using a "Total Area" LISP routine, you can select dozens of closed boundaries simultaneously and get an instant, accurate sum.

You don't need to be a software engineer to use AutoLISP. You can create your own custom scripts using the Visual LISP Editor Open AutoCAD and type in the command line.

(defun c:total-area () (setq total-area 0) (setq ss (ssget "X")) (setq i 0) (while (< i (sslength ss)) (setq ent (ssname ss i)) (setq area (cdr (assoc 42 (entget ent)))) (setq total-area (+ total-area area)) (setq i (1+ i)) ) (princ "Total Area: ") (princ total-area) (princ) ) total area autocad lisp

(Total Area), window-select a whole building wing, and immediately see the result in the command line or an alert box. Conclusion

If you regularly calculate floor areas, site coverage, landscaped zones, or material quantities, a total area LISP is not a luxury—it is a . The time saved in a single week of drafting will pay back the 10 minutes it takes to find or write a basic routine. You can create your own custom scripts using

Instead of typing APPLOAD every session, do this:

: The Lisp routine above costs $0. It runs instantly, doesn't require an internet connection, and works on any version of AutoCAD from R14 to 2026. The time saved in a single week of

AutoCAD’s AREA command works fine for one or two objects. But for multiple areas?

Instead of:

Using fields tied to object IDs allows text notes to automatically update their calculations whenever you run a drawing REGEN (Regenerate). If your design workflow shifts constantly, look into creating LISP routines that deploy dynamic fields rather than static text strings.

This Visual LISP function works on any curve and returns a real number.
