Sweeping 2 lists of curves - why doesn't this work?

It fails because the curve ends / seams are not in the right place

are you sure? when I do the sweep command manually in rhino with baked elements it works.

Increasing the number of perp frames is problematic. I have not found out yet why.

What’s the goal of your definition? There may be a better aproach.

something like this

the script you posted almost works, will work with this. thanks!

Next problem is your text panel with the 1.5708 input which should be replaced with a pi/2

good tip. will use that in the future. still some missing ribs.

One problem I see is the curve in the cyan group (below) is centered in the sweep geometry in top view, which can cause PFrame section curves to overlap. It works better to have the curve generating the PFrames to be at the smallest “center” of the sweep shape so section curves based on planes radiate out without overlapping.

There are other problems even at low number of perp frames.

Sweep2 works fine…
