I am trying to calculate the volume between these two surfaces, preferably through creating a solid that I can then use for subtracting and calculating the difference in volumes.
Ideally I wouldn’t have to convert the topography mesh to a polysurface, but I’ve just not been able to have any joy using meshes and polysurfaces together.
I have tried extruding the outline of the base surface and using the projected outline to trim this surface, then allowing me join all surfaces together into what I would assume would be a closed brep/mesh, but again haven’t been able to crack this.
Any ideas? This has been puzzling me for a few days now.
