Sweeping multiple sections/profiles across multiple rails

I have a set of 17 sections and want to sweep this one set across multiple rails. Since I am not able to sweep a set of sections across a single rail as the rails and sections do not intersect, I’ve created an individual rail for each section within the set, and done this for each of the multiple rails I have.

I now have a list of sections which maps to a list of rails and the data structure of each list is the same however, the sweep1 component still cannot create the sweep. The same definition works so long as I only include a single section profile.

I’ve also tried to sweep each profile over each rail direclty in Rhino and that works. Any direction greatly appreciated.

Graft both inputs to Sweep1.

It’s unfortunate that your sections are so far away from where you want them.

Many thanks!

You almost had it, which is quite an accomplishment in this case. Tricky.
