Making existing buildings "fall" onto a curved non-planar surface.

I am attempting to make a site model with existing buildings on a curved surface, attempting to one day cnc these out of a site model. I have created the existing buildings, and I can project the curves onto the surface, but when I extrude them I cannot cap them, or loft them all (at the same time). How can I keep these buildings as their planar volumes (ie a cube) and make them stay the same shape but intersect the surface as they are going up a mountain? Any help would be greatly appreciated!

Very easy. Post your data

Here is my basic definition i used to create the geometry, i want them to just move up and touch the surface, possibly intersect the geometry so I can one day split the surface and have their imprints upon it. I hope I am clarifying this correctly.

... but :

1. Assume that we do some "modular" (as regards the facades) design (say using some "mega" tiles like the Buchtal Karaijon system etc) and then we apply the same cladding principal on the vertical "members" of the surrounding landscape (walls, stairs, cats, dogs you name itl) : meaning that a vertical grid/"modulus" (kinda like unitizing the move vector) is critical, meaning that the solution requires some additional constrains as well.

2. Assume that the terrain is rocky/remote/whatever and thus the cost of excavations is an also primer constrain, but on the other hand ... using heat exchangers (ducts/pipes) in the foundation level ...

3. Assume that the slope imposes partition constrains as well in order to avoid semi-sinked primary habitable spaces ... blah, blah ...

Notify if you fancy some more elaboration on that (including a solid terrain that allows excavation cost per-estimation etc etc).

best, Peter
