Extract 3D lines from pipes

Question

Hi guys 
 We have an OpenRoads drainage model, and I want a 3D line extracted from the bottom of the outside wall of all the pipes. I am a Civil 3D user, I know how to extract a 3D polyline from a pipe network, but cannot find how to do it in OpenRoads. Can someone please help. 
 Cheers

Currently there is not an automated method to extract the bottom of a pipe. If you can provide some more detail, we can look at maybe adding it to a future version. Or perhaps someone else may have a workaround for the moment.
