Is there a way to generate the principle curvature curves of a surface ?
All of them? Only the ones through a specific point?
Yes at specific points especially the ones at the transition of curvature sign.

Thank You for your reply!
It shows an error but I think there is a component in GH SurfaceCurvature makes the same thing, right?
I wonder if I can draw 2 principle curves on the surface at a specific point .
Yes, I believe the
Principal Curvature component does as I mentioned.
Can you explain this further?
I drew a point and got the closest point on the surface to get its uv values and then calculated the curvature .
I want to draw 2 curves on the surface at this point follow the curvature of the surface.
I still do not know too why it calculates v as 0 for the point on surface.
