# Having rectangles in the same plane as a curve, with multiple curves

Hello,

I hope I can make my issue clear to you.
I projected a lot of rectangles based on some curves, and I want them to have the same direction (plane) as the curve they are projected on, like in the picture. There is an error somewhere in the script, but Iβm absolutely clueless. Has somebody got an idea?

the problem is on the very beginning of the definition
you have 3 branches each containing 37 points, and are looking for the SurfaceClosestPoint providing a list of 4 surfaces:

when you ask a component to do relative operations on two lists of different length, GH will just replicate the last item in the shortest list until every item in the longest list has a match

so, in this case:

Branch {0}
point_at_index_0 β surface_at_index_0 β find closest point
point_at_index_1 β surface_at_index_1 β find closest point
point_at_index_2 β surface_at_index_2 β find closest point
point_at_index_3 β surface_at_index_3 β find closest point
point_at_index_4 β surface_at_index_3 β find closest point
point_at_index_5 β surface_at_index_3 β find closest point
β¦
point_at_index_36 β surface_at_index_3 β find closest point

of course the same happens for Branches {1} and {2}

this concept is clearer with a PointList:

something like this can reorganize the data in such a way points are branched depending on the surface they are projected into (donβt know if this is what youβre looking forβ¦)

the only important thing is that data is organized consistently, expecially when you perform operations that are based on relations

I see what I did wrong in the first place. Organizing this data is quite crucial indeed. Your solution is working by the way. Thanks for helping!

Inno,

Just took a better look at this, and I think there is an error in here.

It looks like the rectangles are not aligned with the curve. I think that the frame does not align with the direction of the curve. Is there any reason for this?

I have no idea of what happens in the definition after the part that I did show you, I stopped looking after the very beginning
