I'm using RoomPlan to create a 2-d layout of a room. Because it's just a single room, I want to present it 'squared' up, see my picture First off, is there any options in the ARView that was used with the scan to sort of zero out the orientation so that it creates a room layout that is not on an angle? If not... Is there a well known mathematical formula to snap this to the closest 90 degrees? I tried just changing the rotation of each wall to snap to the nearest 90 degrees, but it wasn't quite good enough as they no longer joined together cleanly. Perhaps there's an algorithm for doing this while preserving the relative locations of everything?
