Split curves and select outermost curve

[William_Felcone]

Hello,

In my grasshopper file I am trying to split some circles which are drawn at the midpoint of each side of a polygon. I have been able to split the circles, but I only want to select the segments on the outside of the polygon, so that they can be joined to other curves later.

As it is now, shattering the circles and then using a list item component selects 2 exterior curves, and 1 exterior curve. I could select the curves manually with a list, but that would not work when the number of sides of the polygon is changed.

Please let me know if you have any ideas.

Thanks.

P.S If you want the outside arches just use the B output of the Dispatch component.
