I imported the survey x,y,z and wholla - site mesh, very cool. now how do I get topo lines (contours) to print on the site plan? I can bring in the civil's dwg with topo lines and I get all their layers and I just as well builld the mesh from that? I'd also like to check the x,y,z against their topo contours. anyway, is this possible - getting contours from the mesh?
