Hi!

I could not find a tool to grow edge loops so I build one myself. If anybody needs this, take it! (link below images)

My method was to:
1. Promote edge group to points
2. find the ends of each current edge loop
3. With half edge functions, add each next points to array
4. create a string from the array to use in the group sop (e.g. "p0-1-25-64-8 p35-4-3-78")

Hi Scott!

I just tested the GroupFindPath and it works but with a lot of setting changes. For anybody looking to complete full loops that only continues on 4-edge-points, here are the settings:
