Area Autocad Lisp: Total

By default, AutoCAD’s MEASUREGEOM or AREA commands require you to select points or objects one by one. A custom LISP routine offers several advantages:

LISP routines usually cannot calculate the area of an "open" polyline. Use the PEDIT command to close your boundaries before running the script.

Using a is one of the easiest ways to transition from a "CAD Drafter" to a "CAD Power User." It moves the burden of calculation away from your brain and onto the software, where it belongs. total area autocad lisp

(defun c:TOTALAREA (/ ss count total i obj) (setq ss (ssget '((0 . "CIRCLE,HATCH,POLYLINE,LWPOLYLINE")))) (setq total 0.0) (if ss (progn (setq count (sslength ss)) (setq i 0) (while (< i count) (setq obj (vlax-ename->vla-object (ssname ss i))) (setq total (+ total (vla-get-area obj))) (setq i (1+ i)) ) (alert (strcat "Total Area of " (itoa count) " objects is: " (rtos total 2 2))) (princ (strcat "\nTotal Area: " (rtos total 2 2))) ) (princ "\nNo valid objects selected.") ) (princ) ) (vl-load-com) Use code with caution.

Create text that updates automatically if you stretch the polyline. By default, AutoCAD’s MEASUREGEOM or AREA commands require

If you’ve ever spent an afternoon clicking through dozens of closed polylines, manually adding their areas in a calculator, you know the frustration of AutoCAD’s default AREA command. While functional for a single room or shape, it’s a productivity killer for large-scale projects like site plans, floor area ratios, or material takeoffs.

Many scripts will automatically place a text label with the final sum directly into your drawing. Using a is one of the easiest ways

g., converting square millimeters to square meters) or to export the results directly to a text file?

While the script above is a great starting point, professional-grade LISP routines often include:
