Mesh ground surface

Hello everyone, I need to draw the ground on which a building rests for some studies. Can I get the mesh ground surface directly in Rhino, via GH? If so, what procedure should I follow? Thanks to everyone for your patience.

Which plugin?

Hi -

Possibly.
Without more information (and the .gh file?) it’s impossible to be more specific.

I don’t have any project at hand, but I need to reproduce the terrain within a certain radius on which to place the building under study. I would like to understand if I can do this in Grasshopper for example with Ladybug or similar.

From the information that you have provided so far…

Possibly.

No. Those analyze (effects of) terrains, they don’t generate it.

Therefore? How do I model the terrain of a specific area?
