Just a quick question out to everyone. I just hope I'm not going crazy. I swear I found a video out there a few months ago showing some modeling techniques at an interchange. More specifically, it showed some vertical gore tool usage where the ramp connects to the mainline/interstate, some techniques for adding the radii at the intersection of the ramp and minor road perpendicular to the interstate, and then cutting through the mainline/interstate embankment with the minor road beneath. They then created one proposed surface with all of the corridors. If anyone else has seen this and can point me in the right direction, I would appreciate it.
Thanks,
Joe
