Have you tried lofting each group of three curves, one to one in three pairs. You might also have to match their dot products to +1 to ensure that they are not flipped one to the other.

Thanks ever so much for your reply - but would you mind explaining that a little more for me? (sorry, still a grasshopper rookie)

I have internalised some curves in the definition as an example.

thank you ever so much for this - i'm struggling with the math for this though. I'm getting a red box for the evaluate component. It says "left hand value of operator > is Null" - what does this mean? I've tried adapting the math but am frankly stabbing in the dark a bit with this one. I've attached the gh code in case that is easier.

I'm sorry what I gave you is not going to work, because the data structure is different. Plus, the image you posted is misleading because it seems to have depth, when in fact everything is flattened around a cone.

Try and continue from what I did. There is one side missing, but I'm a bit busy...

It looks like you have spent a lot of time on this, thank you so much. I am going through it now. Your help is greatly appreciated! Apologies for the misleading image earlier.
