How to Unify Curve Direction in Grasshopper?

Hello everyone,
I need some advice on how to orient my curves in the same direction.
I’m attaching my Grasshopper definition: despite several attempts, I can’t manage to get all the curves to align in a consistent direction.
If you have any ideas or suggestions, I’d be grateful.
Thank you!

If you have bunch of curves with random direction

the easiest way to solve it is to use a flip curve component with a guide (first curve serves for all here)

if that does not help you can use this py component to orient all curves counterclockwise/clockwise.

also in your case you can use flip curve + circle component as a guide.

Where does this component that allows me to see curve direction come from?

It is from Fennec plugin.

You can decompose it to it’s elements. It has a lot to offer, but I am using only few I need.
