Use Data for Terrain Model creation

After downloading the data, you can now proceed with creating a terrain model in CAD.

1. In AutoCAD or BricsCAD, go to the Plex-Earth ribbon → click on the Create Terrain dropdown box → Terrain from GeoTIFF → load the GeoTIFF downloaded.

2. 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.

3. Click on the Import Terrain button

4. 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.
