Use Data for Terrain Model creation
After downloading the data, you can now proceed with creating a terrain model in CAD.
In AutoCAD or BricsCAD, go to the Plex-Earth ribbon → click on the Create Terrain dropdown box → Terrain from GeoTIFF → load the GeoTIFF downloaded.
In the Import GeoTIFF palette, specify the area by clicking on the Select Area button, then use your mouse cursor to draw a rectangle, and select the desired resolution using the slider.
Click on the Import Terrain button

Select the Surface Type from the options available:
Contour Polylines
Points
TIN Mesh
Civil 3D Surface
Create Terrain Model
For the first four options, CAD objects are directly imported, ready to be used in CAD or other software.
The last option creates a Plex-Earth terrain model, which can be saved in your DWG, and with the help of Plex-Earth, customize the terrain further and also insert the data as CAD objects later on.
