Select the Surface Type from the options available:
Contour Polylines

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.
