Importing KML files into AutoCAD has various applications across different industries, including:

| Problem | Cause | Solution | |---------|-------|----------| | | Coordinates are lat/lon (degrees), but AutoCAD expects meters/feet. | Use Map 3D to assign WGS84 input and project output. Or scale by factor ~111,319 (meters per degree at equator) – but not accurate globally. | | Polygons disappear | AutoCAD closed polyline orientation or complex self-intersections. | Run MAPCLEAN (Map 3D) or use OVERKILL / PEDIT . | | Missing attributes | Vanilla AutoCAD ignores KML’s ExtendedData. | Use Map 3D’s Object Data or export to SHP first. | | Performance slow | Too many vertices or features. | Simplify geometry in QGIS (Vector → Geometry Tools → Simplify). | | Holes in polygons become filled | KML inner rings not supported directly. | In Map 3D, enable “Create polygons with holes”. Otherwise, manually subtract inner boundaries. |
