I am new to the software, but have been playing around quite a bit with the civil cells and have watched the tutorials/videos.
I have a median with left turn lane civil cell, with a ditch in the median. I have a terrain model going from EoP to EoP which is DNC (called Construction), just in order to get the elevation for my median. I also have a terrain model inside the median which is based on the elevation of my median EoP, and two bottom of ditch lines I have offset both horizontally and vertically to the median EoP.
This works fine when the Construction TM is active, but when I clear it the second TM goes wrong, as it is based on the Construction TM to be active.
As such, I can't place multiple of the same civil cells in one corridor as it stops working.
Is my workflow not correct? I based it off the tutorial on Youtube from Bentley, and changed it to fit my needs.
Attached is the dgnlib, the correct civil cell is called test left turn

This may be a case where you may benefit from separating your roadway into different corridors - and not just by length. You can create the corridor for just your mainline pavement, then you can add a corridor for your turn lane and median, which targets that original terrain. You may be able to avoid as many civil cells if you can rethink "what is a corridor".

If you have a design that depends on an active terrain, you can not change your active terrain without messing up the design.You might want to check if it's possible to "hard code" part of your design model to use a specific terrain model name. That way it doesn't matter what the active terrain is.
I recommend keeping your corridor length to a manageable distance and sparingly use civil cells.
