I am looking for the best way and quickest way to create an intersection subgrade. Ideally this would be tied to the intersection created by the intersection tool, so if anything changes the subgrade would change as well.
I tried using the Create Subgrade command found within the Corridors tab but that creates vertical faces around the subgrade up to the finished design, this would create issues for a machine control model. I also tried adding lane edge delineation to my subgrade breaks in the corridor template but this did not work either. I think (could be wrong) the corridor templates will not support "stacked" intersections (finish grade and subgrade).
