I have several mesh of cities coming from photogrammetry software and I need to print them in 3d,
so what I need to do is solidify by filling the volume underneed the mesh surface. The rhino command shrink might help but it just shrink the surface, therefore it becomes a thin solid but the base is still void. I know grasshopper but I never did anything with mesh, would there be a way to make this process automatic? thanks
Ideal case:
Meshes are OK, their footprint is planar and the only thing MIA is to make’m solid. Easy: get the Naked Edges (as Polylines) and Append each Mesh created from these Polylines to the OEM Mesh. Prior storing the closed (hope dies last) result … Combine the Identical Vertices (and attempt to Unify the Normals - good luck on that).

Real life:
Meshes are a mess, faces (worst: non planar portions so to speak) missing, some are non manifold and their footprint is not planar. This may (or may not) require a lot of time to address (I’m talking about the general case + bad Karma where … you know what heppens).
as you said, mesh are a mess, and because of that i use the shrink command that basically get me a closed mesh with a minimal offest form the messy surface, since it would not make sense to patch every single hole or other problems one by one, that 's mainly the reasono of the post. Then I have a closed mesh from which I should get a single dimension mesh from which perform the edge operation you mentioned in the first part of your answer. About your gh definition, the only thing I understand is that you are a ducati fan, I cant write C++ or any other programming language
You mean shrinkwrap?
PS: a screenshot might help…

I also like MV Agusta and NCR Ducatis (nothing to do with ordinary/plain Ducatis). I hear you: what about a Codet Egli-Vincent?
BTW: the thing captured is not C++ (is C#).
Anyway the general case of your issue MAY be a very challenging thing. Post (in R5 format) some bad/ugly/freaky Meshes (why bother with the good/ideal ones? that’s easy)
What is a single dim Mesh? You mean a disjoined one? Or what?
BTW: As Plan Z try MeshLab (many bugs but it’s free).
shrinkwrap has a option to fill holes:
I wasn’t aware of that! thanks!
I mean a surface formed by many pieces but not necessary closed, something similar to what comes out of a 3d scanning or google maps 3d data
Search for extrude mesh… You can extrude it downwards and then trim the bottom flat.
Here’s an example…
