I do have a bunch of vertical nonplanar surfaces that are open (forming arcs from top view) and closed (forming circles from top view) and I do want to sort them, open ones in one side and closed ones in other side. In this example the closed overall surface of “closed” ones are smaller than the open ones, but in other circumstances the closed ones can be bigger than the open ones, so I do need to find a sorting algorithm that works regardless of the size of the surfaces.
You mean something like this?

Yes, this is what I do need. Thank you.
