I have a drainage ditch that I've created a corridor for. Nothing difficult, just daylight to an existing surface. The problem I'm having is with an existing culvert that I need to pick up the drainage from. I created a corridor that will connect into my main channel using the same assembly. I now have two overlapping corridors. Is it possible to trim or clip them so they fit together? Or do I have to detach the and modify the surfaces and leave the corridors alone? I'm using 2011.
It's certainly possible, but it will be a few different regions, targets, and assemblies. Given your sketch, I would be inclined to do this using grading tools instead of a corridor. It will be far easier to clean up the intersection.
