In the attached file I have two sweep paths (rounded corner rectangles). The one sweep path was created using offset so that. while the inner corner is tight. the different in radius is the same as the distance between the rails.
If I use Sweep2 I get this mess in the corner:
If I use Sweep1 there i no mess in the corner. And it looks the same if I use either the inner or outer rail.
I am curious, why is there such a difference?
