I can not rotate some planes I think it’s a really easy step, however I cant locate it like the line direction

what xprod does?
think this produce the same result i’m not sure it was a lucky strike xD

The cross product takes two vectors and produces a vector that is perpendicular to both. So, a vector in the X direction crossed with a vector in the Y direction will give a vector in the Z direction. It’s very useful in instances like these. Here is the Wikipedia entry. Just looking at the illustrations is probably more instructive.

The solution I gave gives consistent results even if the normals are flipped, as in your example. I’m not sure what’s more important to you, the planes along the curve or the planes along the surface edge?
I want to extrude in the X vector from the aligned planes in this case I think could works better along the surface edge
i don’t think this is the best way but it should do the trick…
i guess it depends on what needs to happen further down the line.
