In the earlier version it worked just fine. After the update as some of my models had to be rebuilt the rebuild method in Vertical Design edit seemed to break all of my instructions. I eventually just deleted the Vertical Design and decided to rebuild it. When doing this I could get an instruction to tie from my CL alignment to the EP but it wouldn't keep that instruction for the length of the line. This happened on both sides of the roadway. When creating another set of instructions for the gutter pan and top back of curb, these wouldn't work at all. They flagged no errors, just didn't vertically adjust anything. When viewed in 3d, those lines stayed in ? elevation. They are all linestrings instead of polylines with the obvious exception of the road centerline. I am not sure if I am doing something wrong or if something broke with the tool. Maybe the file itself has become corrupted? I eventually abandoned the Vertical Design tool and built corridors. https://1drv.ms/u/s!Atgw1bevi0UX4wxN5QOADFDSMeq2?e=jhWQAq
Here is a link to my file if you have time to take a look.
