For repeatable, accurate work without paid GIS software.
Extracting contours from Google Earth into AutoCAD is a multi-step process that bridges satellite elevation data with CAD vector environments. Since Google Earth does not natively export DWG contours, you must use intermediary tools or specialized plugins to convert elevation points into usable linework. how to get contours from google earth into autocad
For projects requiring accuracy and speed, the manual method is often insufficient. The professional standard for this task involves using intermediate software or plugins designed to extract the Digital Elevation Model (DEM) data that underlies Google Earth’s visual terrain.

This method uses Google Earth Pro’s "Save Place As" feature and a free online converter to generate true polylines. For projects requiring accuracy and speed, the manual
Use the tool to draw a "dense" zigzag pattern over your entire study area. The more points you click, the more accurate your final contours will be.
Google Earth cannot generate contours natively. You need to use a free tool: GPS Visualizer or OpenRouteService .
This is the most common manual method for users who do not want to purchase additional software. Open Google Earth Pro and navigate to your site.
