| Goal | Best Method | Accuracy | Free? | |------|-------------|----------|-------| | Background satellite image | Method 1 (.jpg + .jgw) | Good (1–5m) | ✅ | | Roads, paths, site lines | Method 2 (KMZ → QGIS → DXF) | Moderate | ✅ | | Elevation contours | Method 3 (GPS Visualizer) | Low (conceptual only) | ✅ | | Survey-grade topography | Use LiDAR or Civil survey data | High | ❌ |
In the Import dialog box, verify the spatial reference layers and click to project the geometry onto your drawing canvas.
If you need help deciding which route to take for your project, let me know:
Use the Civil 3D function to instantly transform these points into an editable 3D terrain surface with contour lines. Method 4: Automated Import Using Professional CAD Add-Ons how to export google earth to autocad
Google Earth Pro can generate contours from its elevation data.
Based on the analysis, the following workflow is recommended for professionals:
Since images don't contain coordinate data by default, they must be "georeferenced" to sit in the correct location. Import Google Earth objects into AutoCAD | Goal | Best Method | Accuracy | Free
Draw a line in AutoCAD between two identifiable landmarks visible on the image where you know the exact real-world distance. Type ALIGN into the command line.
The native KML import preserves the coordinate data with high precision, provided the user configures the correct coordinate system in the AutoCAD drawing settings. The Image Export method is prone to "rubber sheeting" errors if the user does not carefully align control points. Plugin-based methods offer the highest reliability for complex 3D data but incur software costs.
Standard JPEG images do not contain spatial coordinate data. You must scale them manually in AutoCAD using known reference points. Open your drawing file in . Type IMAGEATTACH into the command line and hit Enter . Select your saved Google Earth image and click Open . Method 4: Automated Import Using Professional CAD Add-Ons
It provides seamless background translation features, allowing users to run a direct import command for KML/KMZ files. It transforms vectors into native CAD layers while preserving object databases, attributes, and precise coordinate projections. 3. CAD-Earth
Uses the SPMIMPORT command to bring in KML files with options to fill polygons or create labels automatically.
Use Method 1 (satellite image + world file) . It’s quick, georeferenced, and gives you a visual base to trace over in AutoCAD.
