Curve Seam

hknyzc.3dm (93.9 KB) (14.9 KB) I want the surface normals to point in the same direction.
But I can not use Curve seam component.
Can you help me please

I have no idea what you mean by mentioning curve seam, anyway, this is one of how you would unify curve directions and get Normal directions from them. (22.4 KB)

Thank you so much HS_Kim
