Channel Levels on Longsection

I have created an alignment and longsection and overlayed my assembly to produce the corridor through my alignment. However it is standard practice in the UK to show the channel levels on a longsection. Can this be done?

Can you post a picture of how it should look?

Yes, two possible methods.
If your corridor is a single section with no breaks in the model or additional offset or baselines defining the channels you can select the corridor model and export featureline as profile. This will create a profile on the alignment but it will be static so any tweaks you will need to delete and redo.

For a dynamic profile you need to create an alignment of the channels, create a sudo corridor with edges extending out from the alignment,by a bit then create a surface and hide the two. Now create profile from that surface on each alignment and superimpose on master.
I have not tried this but you may not be able to add any labels on this. So you may have to add manually try it with another profile first and see if it will allow labels.

Otherwise you're into the realms of 3dpolylineToProfile or the landxml hack both of which are not dynamic.

Why not extract featurelines from the corridor and project those onto the profile? They would be dynamic.
