How to convert KML to DXF for CAD workflows
KML to DXF is common, but the real risk is CRS, not the file extension.
Field takeaways
- KML uses WGS84 geographic coordinates.
- DXF CAD workflows usually expect metre coordinates.
- Check datum, zone and units during conversion.
- Preserve layer names.
- MapLab Survey helps open KML and deliver CAD-friendly files.
Why the conversion is not neutral
KML holds latitude and longitude on WGS84; DXF holds plane coordinates in metres. Going between them requires a projection, and choosing the wrong one puts the drawing in the wrong place or the wrong scale.
Project first, then export
Convert to a projected system suited to the area, then write the DXF. Exporting degrees straight into CAD produces a drawing a few units across.
Layers carry, styling does not
Keep layer names meaningful, because colours and line types rarely survive the trip intact.
State the system in the filename
DXF stores no projection metadata, so the EPSG code has to travel in the name and the message.
Try these steps on your own phone.
MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
