How do I modify library nodes' rim elevation at the grate height instead of at the barrel top elevation? Snipped example is Drainage nodes Catch Basin Type A2 Microstation built in library Gutter elevation entered as Rim elevation however structure…

I have been trying to figure out how to add a cell from the cell library to a corridor as a 3D element. Is there a way to do this? (similar to the way the nodes in SUE Modeling operate in OpenRoads)

How do I utilize the cell library (not civil cells) to create 3D elements in a corridor, such as, end terminals for MBGF, signs, etc.? I am using OpenRoads SS4.

I was wondering is it possible to create civil cells for headwalls or end treatments for culverts? I'm aware of SUDA but have never used the product so I'm not sure if this is already possible.
