[Gmsh] Translating Points -> Translates Surfaces?

[Maximilian.Langheinrich at dlr.de]

Hello everybody,

I am trying to model a terrain Volume in gmsh. I do this by first creating a Box geometry by extruding a regular grid and then translating the bottom vertexes to their respective height. Now I encounter problems when I want to generate the 3D Mesh. When the bottom vertices are translated the surfaces they are part of translate as well instead of just resizing and keeping their top edge on the top grid. Is there a way or command to recalculate the surfaces or keep the top edge as it was?

Thank you very much for your help!
