I have inserted a shapefile of contours (that are actually polylines) into an Autocad (Civil 3d 200 drawing. The polylines have an elevation of 0, but each polyline has attribute data attached to it that displays an elevation value. Is there a way to adjust the elevation of the polylines to the attribute data values of each polyline? I have attached a small piece of the drawing that I am using so that you can see what I am trying to do. Thank you in advance for your help and answers.
