Starting with Jeremey’s LearnDynamo Module 2 on Unwrapping Elevations from Model Lines I created a definition to do the same/similar based on Room boundaries.
I’ve got a couple things to work out but the first sticking point is that some of the elevations don’t, and frankly won’t, rotate into the correct position. Generated elevations 3, and 5 in the RVT have their extents stuck to the wall instead of the extended loop I created. When I try and force the rotation of these in Python I can’t get any closer than about 2.5 degrees from perpendicular before the elevation flips and points the opposite direction. I suspect is has something to do with the nature of elevations and walls but I don’t understand why it works in others (even Elevation 4 which should be very similar) and not with these 2 problem children.
Just realized that the same is true of elevation 1. All of the elevations running east-west are problematic. Maybe something in there will lead to the solution.
