3 point arc problem

I am trying to create an arched smooth surface like the one on image 2. Instead, using the same definition with different original curves, I am getting a very irregular shape. Is there any way to solve this?

Thank you in advance

Assuming fr your screencapture, I would say…

  1. Unify your input curve directions first on the same plane.
  2. Don’t reverse the Line component’s “B” input point order.

Internalize your geometry:

Hello! Thank you for your answer!. If I don´t reverse the component B, the curves dont go straight, instead I get crossed lines. Both input curves are already on the same plane

As I already said, if you unify your input base curve directions from the first place in rhino, then you don’t have to reverse any input point order in the downstream of your definition.

Thank you!!!

That is just what I wanted, thank you!!
