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 With the help of Plex-Earth, you can further customize the terrain and insert the data as CAD objects later on.

ℹ️ NOTE: For this tutorial process, it is not mandatory to apply a coordinate system before working with the GeoTIFF, as Plex-Earth will automatically detect it from the file. The coordinate system applied can be changed using the Change Coordinate System button, if needed.

Here is the result!
