SrfSplit sequence

I have curves in a certain order, however after splitting the order changes (does not remain). Why is that? What to do?

After your referenced curves split the surface you’re left with four surfaces instead of one, which is a new (different) list.

Here’s a ‘dirty’ (but not bad) way of getting the order back:

For your future goal(s) get the classic (a bit over simplified) way to do this kind of pair (cause-result).
