I have a set of cross section views in which I have projected feature lines representing existing edge of pavement and existing right of way. I have set the elevations for these feature lines to elevations from surface. Most of the lines fall directly on the surface however in a few of the views the row will either be above the surface or below the surface and not on the existing surface where they should be. I have checked the surface and it is correct. Has anyone else encountered this problem and is ther a fix?
I am using 2012 civil 3d.
