| Error Message | Likely Cause | Solution | | :--- | :--- | :--- | | ; error: bad argument type | You selected a non-curve entity (line, arc, text, block). | Modify your ssget filter to exclude those. | | ; error: no function definition: VLAX-CURVE-GETAREA | Visual LISP extensions not loaded. | Add (vl-load-com) at the top of your LISP file. | | Total = 0.00 | Polylines are not closed or are self-intersecting. | Use PEDIT → Close. For complex intersections, use REGION first. | | Area is huge (e.g., 1e9) | Drawing units are millimeters, but you expected meters. | Divide total by 1,000,000 in your LISP. |
