Is it possible to project a line on a surface (made with toposhaper)? What I would like to accomplish is to project the lines, which are now under the surface, and hence non-visible on the surface. The straight lines show the the lot boundaries.
@tt_su, thanks for the suggestion! How would you do it? I tried the extension “Extrusion Tools” / Extrude Edges by Vector to Object. What happens is that the extrusion stops at the group that contains the surface, even if the object is hidden.
