Total Area Autocad Lisp ((new)) -

;; Example: If drawing units are millimeters, show square meters ;; (princ (strcat "\nSquare meters: " (rtos (/ total 1000000.0) 2 prec)))

;; Convert to common units (optional - adjust conversion factor) ;; For meters to square meters: no change ;; For millimeters to square meters: divide by 1e6 ;; For inches to square feet: divide by 144 ;; For feet to square feet: no change

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). total area autocad lisp

that doesn't just calculate the sum but creates an auto-updating MText field. If you modify the original object, the total area value updates automatically. MultiArea: A routine from ESurveying

;; Display results (princ "\n========================================") (princ (strcat "\nTotal Area of " (itoa cnt) " object(s):")) (princ "\n----------------------------------------") ;; Example: If drawing units are millimeters, show

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.

If you need more than just a simple sum, consider these variations: MultiArea: A routine from ESurveying ;; Display results
