: Creates an MText object containing a dynamic "Field Expression". If you modify the original shapes, the total area updates automatically after a AMO (Add Multiple Objects)
Save the file. Name it TotalArea.lsp . Ensure the extension is strictly .lsp and not .lsp.txt . Step 2: Load it into AutoCAD Open your current drawing in AutoCAD. Type in the command line and press Enter . total area autocad lisp
;; Step 1: Create a selection set (setq ss (ssget '((0 . "LWPOLYLINE,CIRCLE,ELLIPSE,SPLINE,REGION,HATCH"))))
The text placement portion of the script uses the active text style's default height. If your active text style has a fixed height set to 0 , AutoCAD will prompt for height during execution, which may break the automation sequence. Ensure your active text style has a pre-defined height, or tweak the _-text macro parameters in the script to match your specific template workflows. Conclusion

When dealing with busy, complex blueprints, use the LAYISO command to isolate the boundary layer containing your target objects before running your total area LISP. This minimizes the risk of grabbing unrelated geometry.
Polylines that loop over or cross themselves will cause calculation errors. Use PEDIT or redraw clean boundaries if your script skips a shape. You should see a message at the bottom
An AutoCAD LISP for "Total Area" is a custom script used to automate the summation of areas from multiple selected objects, such as closed polylines, circles, and hatches . While standard AutoCAD commands like
Copy the following text exactly into a blank Notepad file. Save it with the name TOTAREA.LSP (ensure the extension is .lsp , not .txt ).
