Orienting breps on ruled surface

Dear all,

I am currently working on a filter facade on ruled surface. The aim is to have the elements that compose the filter aligned with the rulings of the surface (as in the rhino file attached)

I made a grid on a doble curvature surface using lunch box tool and the I oriented the brep elements using the normal vector at each point of the grid.

However, due to the diverse XY direction of the normal planes, not all of the breps are aligned properly. And even though, the elements are centred in each face normal and not following the rulings.

In there a way to make a small rotation of the planes in order to make them follow the rullings?

Thank you in advance.

Just using the frame output of Evaluate Surface should work.

Thank you Kim! That was helpful

It will work if the bending of the surface is not too big. However, what I ment in my previous post was how to orient all the breps of each column with the single rule that crosses the surface.

Thank you again!

Check this as well.
