The documentation is a bit contradicting, e.g. in GRASS7 programmer's manual it says "Face and kernel are 3D equivalents of boundary and centroid...", but edge is commonly used as 2D/3D boundary (Vector network analysis, general graph theory). Thus for 3D we would have edges in the coor file, faces (3D areas) are going to be constructed from edges and volumes are going to be constructed from faces and kernels. Is this nomenclature ok?
