While QGIS can read some DWG files, it prefers DXF. Open your DWG in a free viewer like DWG TrueView (Autodesk) and save it as a DXF.
By default, AutoCAD lines sit at elevation Z=0 . Google Earth has hills and valleys. Your building will look like it’s floating or buried.
Before initiating the transfer, the user must address two critical challenges inherent to CAD-to-GIS conversion:
Simply double-click your new KML file. Google Earth will fly you directly to the location. Your polylines, blocks, and even 3D extrusions will appear draped over the terrain.
Load the resulting KML into Google Earth Pro. If your drawing was "un-geolocated," it will appear at 0,0 latitude (off the coast of Africa). You will need to manually drag and rotate it using Google Earth's "Move" tool (right-click the KML > Properties > Altitude > "Relative to Ground").
