Fixed: Creating collision-outline for Obstacles using IsoVist

Gh 0.9.0076
Am trying to visualize the outline curves from an IsoVist sampling. I have a collection of points from where I cast the rays and a collection of obstacles. I have a inconsistency when I use different numbers for the sampling origin. I attach the gh file, where with 4 points the effect is what I am looking for, yet with 5 sampling points the sorting gets mixed-up. Any tips/suggestions how to get this fixed?
The color sorting for the rays works fine, yet creating the white outline-curve doens’t

The problem is, before using Partition List, you’ll need to regroup the ray intersection points and after that sort them along each circle…
