Hello,

I have made a set of points created from intersections. I need to group and sort these points by their X coordinate, and connect them together using lines so I can loft them.

I have attempted to use CSet and MIndex to group the points with the same index, but it runs into problems with 2 or more distinct branches. The second branch loft correctly, but the first one seems to group the first set x coordinate in the first list, but uses the second branch x coordinates after. Have I set the structure correctly?
