To Import Kml File In Autocad — How

KML files, commonly associated with Google Earth, are a standard format for storing geographic data such as points, lines, polygons, and images. Directly opening a KML file in vanilla AutoCAD is not supported. However, with the correct workflow—using conversion tools or AutoCAD’s specialized Map 3D and Civil 3D versions—you can successfully import this data as editable drawing objects.

Always verify a known distance or coordinate after import using a reference point (e.g., a surveyed benchmark or Google Earth’s ruler) to confirm correct transformation. how to import kml file in autocad

| Issue | Solution | |-------|----------| | Coordinates are in degrees but you need real-world units | Use or SCALE based on two known points with real-world coordinates, or re-import with correct projection. | | Lines/polygons are exploded or unjoinable | Use PEDIT → Join to create continuous polylines. | | Missing attributes (names, descriptions) | In Map 3D/Civil 3D, use MAPIMPORT with "Import polygon as closed polyline with object data" to retain attributes as extended entity data (EED). | | Drawing is extremely large/small | The units are in degrees (approx 111,000 meters per degree). Use SCALE with a factor of 1/111319.9 to convert decimal degrees to meters approximately, but a proper projection is the correct solution. | Summary Table of Methods | Method | Best for | Requires | Accuracy | Ease | |--------|----------|----------|----------|------| | AutoCAD Map/Civil 3D | Frequent GIS-CAD workflows | Map/Civil 3D license | High | Easy | | QGIS + DXF export | Users with no GIS license but need control | Free QGIS software | High | Moderate | | Online converter | Quick, non-confidential, small files | Internet | Medium | Very easy | | Google Earth Pro DXF | Very basic, single-feature KMLs | Free GEP | Low | Moderate | Final Note If you regularly work with geospatial data (KML, SHP, GeoJSON) in AutoCAD, upgrading to AutoCAD Map 3D or AutoCAD Civil 3D is the most efficient professional solution. For occasional needs, the QGIS workflow provides a robust, no-cost alternative that respects coordinate system transformations—critical for maintaining spatial accuracy.
