Convert Watertight Mesh to Solid

I am interested in converting a watertight mesh (Toolkit Mesh) to a solid. I have searched the forum and only found methods for converting topography-like meshes to solids using thickening in the downward direction. I guess what i am curious is is there is some method for enclosed (watertight) meshes like Mesh.Fill that essentially fills the void space in a watertight mesh to get a solid rather than a mesh.

Best way to intersect solids with a mesh

Hi everyone, I need to intersect multiple Dynamo Solids with an imported mesh from a Revit Topography to calculate the excavation volume. I faced some difficulties here. The mesh Toolkit is not working with my mesh, converting the mesh to a Dynamo mesh by using the Vertices and FaceIndices also didn’t work. Has anyone an idea how to do this? I’m using Revit 2016/Dynamo 1.0.0/MeshToolkit 1.0.0. I can update any of this if this solves the problem. Thanks, Fabian
