Total Area: Autocad Lisp

The script prompts you to select objects by automatically selecting all polygons, polylines, circles, and arcs in the drawing. It then calculates and displays the total area of these objects.

: A widely used routine (often attributed to Jimmy Bergmark) that calculates the total area of all selected objects at once. It works on polylines, circles, ellipses, and splines. A2F (Area to Field)

;; Alternative: Quick total area with selection window (defun C:TAQ ( / ss total area obj) (setq ss (ssget '((0 . "CIRCLE,ARC,ELLIPSE,LWPOLYLINE,POLYLINE,REGION,HATCH")))) (setq total 0.0) (if ss (repeat (setq i (sslength ss)) (setq obj (vlax-ename->vla-object (ssname ss (setq i (1- i))))) (if (vlax-property-available-p obj "Area") (setq total (+ total (vla-get-area obj))) ) ) ) (princ (strcat "\nTotal Area = " (rtos total 2 2))) (princ) ) total area autocad lisp

In the daily grind of drafting and quantity surveying, calculating areas from polylines can be one of the most repetitive and error-prone tasks. Standard AutoCAD commands (like AREA with the Object option or LIST ) are functional but limited—they only give you one area at a time, and they don't sum multiple selections. It works on polylines, circles, ellipses, and splines

: These are excellent but often cost $200–$1,000 per year.
