Hi @danielbent
Thanks for your solution.

I can understand that take the midpoint of the curve and select the closest, bot how the listitem working?

ClosestPoint can return the index of the point in the cloud list in relation to the point it searched from. By using Listitem + these indexes you can give the lines the right oder.

You don’t need explode and join , isotrim already give surfaces
and you need align seams
