I am new to autocad civil 3d and i am using 2012 edition.
I am designing a road. My problem is that my selected assembly which contains daylight.general having a ditch at right side, does not touches the topo/NSL or Ground surface and ends above or below it. I have set the target as NSL and still does not work. Also the corridor boundaries are set to day for both top and bottom surfaces of the corridor.
Here is the section. the problematic parts are circled red.
