Reverse direction & reset counting

Hello,

I get these V lines from the section of a lofted Srf with Planes.

The curves don’t have the same direction, so I flip them, according to a base curve that has the start point at the bottom. But not all get the right direction.

Any ideas how that can be corrected?

Does anyone know how to reset the counting of the curves, so that they are consequent & not opposite?

 

 Thanks in advance

With a bit of trickery its possible. I check the distance between the first point of the guide curve and those of the other curves. Then according to a threshold it will reverse the list of control points to rebuild the curve. Not ideal, but it works. ;)
