Sweep many rails with profiles

Hello, I’m new at grasshoper and I may need some help. I’m trying to draw a roof with iron beams. I used the command sweep to make my structure by using a surface. The main beams ( the bigger ones) are fine but I don’t like the secondary beams. I would like to orient them perpendiculary to the main curve and not in the Z axis. I tried differents options but i never succed to do better than that. Do you think you can help me ? TOITURE.gh (11.1 KB) TOITURE.3dm (50.2 KB)


Use your normal directions of base surface.
