If you are using full AutoCAD (not LT), follow these steps:
Method 1: Quick One-Time Load (Fastest)
Method 2: Permanent Load (Add to Startup Suite)
Use a LISP that outputs in acres to 4 decimal places, and include a check for polylines with bulge segments (curves). The basic vlax-curve-getArea handles arcs correctly. total area autocad lisp
You might ask, "Doesn't AutoCAD 2025 have a built-in Total Area tool?"
AutoCAD's Native DATAEXTRACTION : This works, but it requires a 12-step wizard, creates an Excel table, and is overkill for a quick sum.
AutoCAD's QUICKPROPERTIES : Shows area for one object, not total. If you are using full AutoCAD (not LT),
Third-party plugins (e.g., AreaCalc, LandFX) : These are excellent but often cost $200–$1,000 per year.
AutoLISP (Free) : 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.
For a professional drafter, learning to load and modify a simple Lisp like TOTAREA is a rite of passage. It is the single highest ROI automation you can implement today. Method 2: Permanent Load (Add to Startup Suite)
This routine links the total area to a FIELD or RTEXT so that if you stretch a polyline, the total updates automatically (requires advanced Visual LISP using reactors).
If you want control over every detail, writing your own 10-line LISP is straightforward.
(defun C:MYAREA ( / ss total obj area cnt)
(setq ss (ssget '((0 . "LWPOLYLINE,POLYLINE,CIRCLE,ELLIPSE"))))
