See the follow file for details: https://www.filedropper.com/filemanager/public.php?service=files&t=757744643cd3d3972ae382af4a4deb91 . I create a spiral structure which is smooth and beautiful, then scale it up by a factor of 10. Once it's scaled up, the geometry has changed. Can anybody tell me why, and if there is a way of avoiding it? Thanks!
