Convert easily your DWG/DXF files to KML/KMZ for Google Earth quickly and accurately. You can export the entire drawing or only a selection of specific objects, preserving the structure, layers, and styles of the original CAD file — all in a single step.


Available for AutoCAD, BricsCAD, ZWCAD and GstarCAD


1. The drawing must be georeferenced

  • Run SPMSETCRS command and check if the drawing has a coordinate system assigned, if not, you can search by code, name or location (country, city, …).
  • For confirm the drawing is well georeferenced, run SPMBGMAPSHOW command, select any background map and check if the map matches the drawing location.

  • For reviewing and editing the attached data, you can use the SPMDATATABLEGRID command.

3. Convert to KML or KMZ

  • Run SPMCREATEKML command.
  • Select the objects to export.
