I'm attempting to create a takeoff report and I believe that I have everything set up correctly, however, the original ground surface is not being built off of the contours I've given it. All of the site improvement quantities are being generated but the mass earthwork quantities are coming up as zero because the original surface is not being built. Is there something I need to do different for this to work?
P.S. The contours I'm trying to use were generated off a surface that I received from an engineer so I was not directly given the contours I want to use for the original ground surface. I'm not sure if this makes a difference.
Is it because my contours are polylines and not linestrings? If so how do I convert multiple polylines to linestrings?
