I’ve project multiple enclosed curves onto a topo mesh and would like to split them with the mesh so I can apply different materials to my topography (i.e., roads, sidewalks, etc.)
When I try to split rhino triangulates more on the outside of my enclosed curves and then splits it from the mesh but not the part I would like split. Is there a way to get a clean split without using a NURB surface? I have a rigid topo with walls and can’t get a NURB surface to accurately represent my topo.
If Rhino isn’t able to split the mesh correctly is there a tool like Google Sketch-up’s drape command in Rhino?
