List item return different items

[omercnaani]

hi, I have surface that I split by curves (via split brep). when I’m trying to get the first index of the split brep I get the brep (index 1). Unfortunately all the brep that I get are right except one of them. if in the 10 brep the 1st index is A, in the 11 brep the 1st index is B. I have no idea how can I fix it. any suggestions?

You just need to use Sort Points to sort your surfaces (the white group).
