Columns Crossing

Does anyone know how to solve columns crossing? I have curves representing my floors and I want to divide each curve into points and use those points to form columns. However at the very top the last floor is crossing each other. I tried replacing the top curve and flip it but somehow it still doesn’t work. Please see image for result and grasshopper flow.

Probably your last section curve is flipped.
Also, it seems you deliberately flipped it yourself!

Try with Flip curve:

So you can use the first section curve as “Guide” to flip all the section curves into a uniform direction


Thank you. This was is a much better way to do it and it worked.
