Re: Calculating excavation volume in multiple levels

Thank you for introducing TessellatedShapeBuilder,
however, we need some "face" to create a solid using TessellatedShapeBuilder, and we don't have any faces, just a mesh with its triangles.
as far as i know, we can convert a face to a mesh by using .Triangulate method, but not from mesh to face. it seems logical because every triangle itself is a standalone face and each of them may be in a different plane, so it is not possible to convert a mesh to face.
i think i should give up creating a solid from topography and it seems the only solution is to work with xyz points of triangle vertics as u mentioned.
