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.
But here’s the catch: You need a conversion bridge. This guide will walk you through the three most reliable methods to get your CAD data onto the globe. Method 1: The Native AutoCAD Route (Best for Precision) If you have access to AutoCAD (Full Version, not LT) with the Geolocation feature, this is the most accurate method.
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.
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.
Open your drawing in AutoCAD. Type GEOGRAPHICLOCATION (or GEO ). A map window will appear. Search for your project address or manually pick a point on the map. This assigns real-world latitude/longitude (usually UTM or Lat/Long) to your drawing.
If you are a student or hobbyist without a CAD license, . It has a learning curve, but it is powerful and free.
For architects, civil engineers, and urban planners, there’s nothing quite like seeing your 2D AutoCAD design overlaid on the real world. Whether you’re checking a building’s solar orientation, presenting a proposed subdivision to stakeholders, or simply visualizing a site plan in context, Google Earth Pro provides the perfect free tool for the job.
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"). Method 3: The Online Converter (Quick & Dirty) For simple 2D linework, online converters work fine. Use services like MyGeodata Converter or GPSVisualizer .
