Kml Autocad Import Jun 2026
| 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. |
To import KML files into AutoCAD, you'll need to use the MAPIMPORT command. Here's a step-by-step guide: kml autocad import
| Task | Command / Tool | |------|----------------| | Import KML directly | MAPIMPORT (Map 3D/Civil 3D only) | | Set drawing units | UNITS | | Set coordinate system (Map 3D) | MAPCSASSIGN | | Clean up duplicate geometry | OVERKILL | | Join polylines | PEDIT → Join | | Convert lat/lon text to points | _MAPPOINTFROMTEXT (Map 3D) | | | Polygons disappear | AutoCAD closed polyline
Select the layers you wish to import. Most KML data is stored in the "Placemark" layer. | Use Map 3D’s Object Data or export to SHP first
Before importing, ensure your drawing has a coordinate system assigned (e.g., using the MAPCSASSIGN command).
