Sorry, I didn't fully get that, please explain again.

What do you mean by multi-domain polyhedron? Polyhedron_3 is a 2-manifold
and it can have multiple components. If you mean that it has volume with
inner spaces, then you probably need tets (mesh_3). The example you provided
just contains an open mesh (is it even a manifold?) and a box. Maybe you
should provide a better example.

If you define your shapes as zero level sets a distance function, I think
that bool ops should be straight forward, and then you could extract a mesh.
Tell me if you don't understand what I mean.

CGAL should be able to perform bool ops on multi-component surfaces.
Otherwise, just do it component at time.

I'm not sure about carve lib capabilities. But if you want me to test
something, then provide meshes.
