We recieved a set of contours from a city, all with z coordinates, all on the same layer, no text or labels. They are all 2 foot contours. I need to extract out all the ten foot contours. Anyone have a lisp or something that will extract out and relayer the tens? Or suggestions on where to search? I'm hitting the cad sites but not coming up with anything.
Thanks.
