Luckily someone in the following forum post has shared the code within the “group_curves” node in the following forum post: Extracting closed Polycurves from given Surface - #2 by Mohammad_Nawar
I was able to get it to work in my script, so I finally have joined polycurves that I am able to offset. However, I need a way to filter a polycurve that is contained within any polycurve that exists in a list. This is so letters like A and P only offset the exterior lines, not interior.
