Open QGIS. Go to Layer > Add Layer > Add Vector Layer . Source type = "File". Select your DXF file. You will see a list of entities (Point, Line, Polygon, etc.). Select all that apply.
In Google Earth Pro, right-click your imported layer > Properties (or "Get Info"). Go to the Altitude tab. Change the drop-down from "Clamped to ground" to "Relative to ground." This keeps your CAD lines flat but pressed against the terrain surface. For 3D buildings, use "Absolute" and set a base height. Common Pitfalls & Solutions | Problem | Likely Cause | Fix | | :--- | :--- | :--- | | Nothing appears | Your CAD objects are in Paper Space, not Model Space. | Move everything to Model Space (use CHSPACE command). | | It lands in the ocean | No geographic coordinate data. | Manually reposition in Google Earth (Right-click > Properties > Move/Resize). | | Lines are invisible | White lines on white snow/clouds. | Change your CAD line color to a dark, solid color (e.g., RGB 0,0,255 blue) before exporting. | | Huge file size | Too many hatch patterns or complex blocks. | Explode complex blocks and remove hatches. Use simple polylines. | Final Verdict If you are a professional, use Method 1 (AutoCAD Geolocation + KMLOUTPUT) . It takes 30 seconds and maintains perfect spatial accuracy. how to import autocad to google earth
If you are a student or hobbyist without a CAD license, . It has a learning curve, but it is powerful and free. Open QGIS
Your CAD likely has no coordinate system. Right-click the layer > Export > Save Features As . Format = "Keyhole Markable Language [KML]". Crucially , click the globe icon next to CRS (Coordinate Reference System) and select WGS 84 (EPSG:4326)—this is what Google Earth uses. Select your DXF file
Once you master this workflow, you will never design in a vacuum again. Seeing your parking lot overlaid on actual satellite trees, or your building shadow cast across a real street, changes how you think about site design entirely. Go explore.
