and edges, just hide the mesh to avoid this. To avoid a long wait when a
geometry with many faces (or edges) is displayed, the number of faces
(edges) shown at a time is limited by the value of "Sub-shapes

If faces/edges without layers are specified, the element layers are
not constructed on geometrical faces shared by several solids in 3D
possibly being internal faces/edges within the whole model.
