Open the resulting DXF in AutoCAD. Use the JOIN or PE (Pediting) commands to clean up the resulting polylines . 2. Specialized Plugins (The Professional Workflow)
Finally, the generated contour lines are exported from the GIS software as a DXF (Drawing Exchange Format) file, a universal vector format. The user opens AutoCAD, creates a new drawing, and uses the IMPORT or OPEN command to load the DXF file. The contours arrive as polylines, each typically encoded with its elevation value in the Z-axis property. To ensure accuracy, the user must then georeference the drawing: using AutoCAD’s ALIGN or GEOGRAPHICLOCATION command, they match a known point on the contours (e.g., a road intersection) to the same point on a georeferenced image or basemap. Once aligned, the contours can be used for surface creation, volume calculations, or as underlays for site design. contours from google earth to autocad
Convert the file and download the results as a or CSV containing Easting, Northing, and Elevation. Import to AutoCAD/Civil 3D : Open the resulting DXF in AutoCAD
Best for: Small areas, individual building sites, or when you do not have plugins. To ensure accuracy, the user must then georeference
