In the worlds of CAD (Computer-Aided Design) and GIS (Geographic Information Systems), file compatibility is the eternal struggle. Architects, civil engineers, and urban planners often work in DWG (AutoCAD’s native format), while environmental scientists, drone operators, and Google Earth enthusiasts rely on KML (Keyhole Markup Language).
Zamzar is a veteran in file conversion. While it’s a general tool, its DWG→KML engine handles 2D geometry well. Note: It does handle 3D extrusion or complex blocks perfectly. dwg to kml online converter free link
Pick one of the free links above, upload your CAD file, and see your floor plan or site map floating accurately over real satellite imagery in Google Earth, all in under 60 seconds. Disclaimer: Free online converters change their terms periodically. If a link is no longer free, try the next one on the list. For sensitive or proprietary DWG files, always use offline software like QGIS to avoid data privacy risks. In the worlds of CAD (Computer-Aided Design) and
| Tool | Platform | Learning Curve | KML Quality | | :--- | :--- | :--- | :--- | | (with CAD plugin) | Win/Mac/Linux | Medium | Excellent (preserves attributes) | | Google Earth Pro (built-in importer) | Win/Mac | Low | Good (but struggles with complex DWG) | | Blender + GIS add-on | Win/Mac/Linux | High | Excellent (3D extrusions) | While it’s a general tool, its DWG→KML engine
AideCAD is purpose-built for this specific conversion. Unlike general file converters, it understands CAD layers, blocks, and georeferencing (if your DWG contains经纬度/UTM coordinates).
MyGeodata is a specialized GIS cloud converter. It reads DWG’s internal coordinate system (if defined) and reprojects it to WGS84 (the standard for KML/Google Earth).
