In AutoCAD Map 3D, use the MAPCSASSIGN command to choose a specific projected coordinate system (e.g., State Plane or UTM). This ensures that any imported data aligns perfectly with your site's actual position. 3. Importing KML and KMZ Files
| Issue | Solution | |-------|----------| | Lat/lon values are very small | Scale X,Y by 111,319.9 (meters per degree at equator) | | Coordinates appear far from origin | Use BASE command to relocate near 0,0 | | Elevation (Z) missing | Extract Z from KML or use ELEVATION command in Civil 3D | google earth coordinates to autocad
Google Earth saves data as KML or KMZ files. Bringing these into AutoCAD requires different approaches depending on your software version. To Import Keyhole Markup Language (KML) Files | Autodesk In AutoCAD Map 3D, use the MAPCSASSIGN command
Use the POINT or CIRCLE command. When prompted for a location, type the X coordinate followed by a comma, then the Y coordinate (e.g., 663323.11, 2736022.26 ). 2. Native AutoCAD Geolocation Tools Importing KML and KMZ Files | Issue |
, it specifically automates the insertion of georeferenced images and objects with high resolution. Final Verdict Feature Manual Method Third-Party Plugins (e.g., Plex-Earth) Cost Free Paid (Trial usually available) Speed Slow; requires manual entry Instant; supports copy/paste Accuracy High (if UTM conversion is correct) High (automated transformation) Best For One-off small projects Large-scale or frequent site planning Important Note
