Create sweep solid tangent to surface

panels1.gh (46.1 KB) I am having issue sweeping members along curved surface so that it will be tangent and members are always parallèle to surface. Some kind person helped me revising grid (white one is originally have) to consistent shape, but now I am having this issue instead. Does anyone know how to work with this

You need multiple perp frames along the sweep rail and align the frames to the surface you used for the pattern.

I have a group on the right which was working with different script, but struggling to make them work together

I would like to separate them into 4 different lists depending different directions, and sweep like you said. How can I sort the list?
