3D mesh with 2D constraints

I used the tool "intersect a surface with a line" to generate a mesh for a 2D geometry.
Is there a similar tool for 3D cases, something like 'intersect a volume with a surface' type of tool?

A direct tool to intersect a volume against one (or multiple) surface(s) doesn't exists

What exists is a tool to intersect surfaces against surfaces.
Geometry->Edit->Intersection->Surfaces
Once all is intersected, maybe the sub-surfaces separate your volume in two or more parts,
then you can use
Geomtry->Edit->Divide->Volume->Split
to split the volume in two volumes, selecting the volume and the collection of surfaces that divide it in two parts.
Not: the split tool won't try do find any intersection of lines or surfaces, all must be intersected and well connected to be able to split the volume.
