We have found 3 software records in our database eligible for .dwg to .kml file format conversion.
CAD/3D models exported in KML (Google Earth) format is not that uncommon nowadays, so many tools actually support such support. While not every software might support KML/KMZ format natively, many can add support for these formats with plugins or similar extensions. In case of dwg to kml conversion, it's probably a matter of export of vector graphics or geometry.

DWG
A dwg file extension is used for standard CAD file format, originally used by AutoCAD. A DWG is a proprietary format and can only be created in AutoCAD. Other CAD programs can usually import it but not create its proprietary form. Because of this, DWGs are often exported to DXF interchange format so that they can be seamlessly used in other CAD programs.
KML
Files with kml extension can be usually found as navigation/map files saved in Google's KML (Keyhole Markup Language) file format.
