I’ll ask here because it’s the same file.

I’m having difficulty figuring out how to index these items so I can isolate them to work with them. Well, two things need to happen:

1.) Isolate those curves that lie on the surface seam,

2.) Explode those curves and again isolate and remove the middle curves so I can join the remaining curves on either side of the seam to form a complete hex.

I’m getting swamped in list indexes for what seems like a relatively simple thing. If those patterns on the seam were in a series (index 0 to 7 for example) it would be straightforward, so how do I arrive at the index pattern that selects just those curves?
