Trying to extrude the different paths but it locks onto the road. Drawing was imported as a dwg from autocad
Profile edges like that usually imply there are gaps in the loop of edges. Zoom in close to check and close the gaps with the Line tool. There could also be forks in the edge sequence which need to be cleaned up. Sometimes it’s a case of not all edges being in the same plane. And in some cases simply tracing one of the profile edges in the loop will sort it out.
