I'm creating a pipe network which has an associated reference surface. However, when looking at the network details the minimum and maximum cover is showing as 0.000m and the start and end cover appear to have the same cover (just -0.08m).
The network was designed in WinDes and imported into Civil 3D. I have checked cover levels in the areas and the pipes should be showing with a minimum cover of at least 1.200m
Does anyone know what might be causing the pipe to not be picking up the correct ground level?
Thanks,
Martyn
