Making an arc between each of the curves

I’m trying to make the arc as shown in the photo attached however I am having trouble understanding how lists work. I tried taking a stab at it however to no avail.

Here’s a simple solution:

In order to build the ‘arcs’ you need a tree structure.

You start with 1 closed curve and divide it into 100 segments. These segments will have a path index from {0} to {99}. The curve start and end point are projected or pulled to your surface. Using a midpoint component doesn’t require sorting or culling anything.
