I have a corridor that creates 3d lines ie Ditch Flowlines. I want to extract them back out to an alignment with profile. What is the best way to get that information?

Can you Project the features onto your profile?

This is Openroads.  I have created an alignment and profile and processed templates.  The solids are created in the 3d model along with the line work from drop to drop.  The element(linestring) is the result of the corridor and has an associated profile or 3d information since it's in a 3d file.  Our drainage guys need that information to refine the now special ditch and send that back to the Prime as an alignment with profile in Openroads or as geopak GPK.
