The conversion primarily involves changing the format of the coordinates.
If you are using or Civil 3D , you have built-in tools to handle coordinate transformations and KML/KMZ files directly. how to convert google earth coordinates to autocad
: Enter -DWGUNITS in the command line to ensure your project units match your source data. The conversion primarily involves changing the format of

| Issue | Solution | |-------|----------| | | Always project Lat/Lon to a local projected system (UTM, State Plane) before entering AutoCAD. Never use degrees as X,Y. | | Elevation (Z) | Google Earth elevation is ground surface. Use MOVE → 0,0,0 to flatten to Z=0 if not needed. | | True North vs. Grid North | Google Earth uses True North. AutoCAD drawings often use Grid North. For large sites (>1 km), adjust rotation using the ALIGN command with two known points. | | File too large | Google Earth exports can contain many vertices. In AutoCAD, use MAPIMPORT → set "Vertex reduction" to 0.5 m tolerance. |
