Hello, I am trying to sort the list by y coordinate. I have already searched the methods online and followed them. All of them are not worked. What is the problem? Thanks

It looks like the sorting isn’t your problem. What does the warning say?

Thanks for your reply. It is said the the direction of lofting is wrong or opposite. So I guess I need to sort the list by y - coordinate first. Is it correct?

Possibly. It’s hard to tell without seeing all your data.
I’m not sure how Point.Y would work on a Curve to begin with, but I would recommend flattening your list of curves, then using SortByKey and GroupByKey to get your curves in order.

I will try it first. Thanks !
