Flip Matrix Cull Index

Hi everyone, I am trying network a surface with topography lines, and in order to do that I need two directions. So I divided my topo curves and then used flip matrix in an attempt to connect the points with polylines. But! The lines want to connect back to earlier items in the list. I tried using cull index, and i can't get it right. Can somebody please explain to me what I am doing wrong?

Hi.
First of all, you should unify your curve directions and the order of referenced curves.
Also, there are some too short or closed curves among them that aren't fit to even division.
It may not be what you want BTW, if you don't mind a mesh solution then, I would suggest this method using "Delaunay Triangulation".
