Alignment and Surface Profile - Corridor Design

Question asked by Tyler House on Jul 29, 2019



I have an alignment starting at station 289+20.96, I need to design a corridor off a surface profile. Only work around I've found is the create a linestring out of the alignment and elevate it to the surface and create a new alignment and profile out of that however if i change the start station the vertical grade breaks don't change with it. I ended up adding a station equation at the start and that seemed to let me design my corridor off the correct stations and compute my super elevation data. Anyone have a work around for this, or a better way to approach using a surface profile for a corridor project?
