This is where (List Processing) becomes a game-changer. By using a custom LISP routine, you can calculate the total area of multiple objects instantly, saving hours of tedious work and reducing human error. Why Use a LISP Routine for Total Area?
So stop adding areas manually or using clunky workarounds. Copy the TOTAREA code above, load it right now, and watch your efficiency soar. Your future self—and your deadlines—will thank you. total area autocad lisp
Verify that the bottom of the dialog box states "TotalArea.lsp successfully loaded." , then close the window. Type into the command line to run the tool. This is where (List Processing) becomes a game-changer
(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) ) So stop adding areas manually or using clunky workarounds
(repeat (setq i (sslength ss)) ... )
Change precision by modifying the prec variable (line ~15):
: The ssget function prompts the user to select objects on screen. The associated association list acts as a strict entity filter. The script strictly allows the selection of LWPOLYLINE (lightweight polylines), POLYLINE (old-style 2D/3D polylines), CIRCLE , HATCH , and REGION entities. Open lines or text are automatically ignored to prevent calculation errors. 3. The Calculation Loop
