This is a classic connectivity game (requires a mesh EV tree, the V List and the E List). Kinda the stuff that Sandbox does.

For a given edge in the EV Tree (branch index corresponds to E List index) we have the connected vertices indices (in the V List). The only thing remaining is to find (or "map") these vertices to the List1, List2 and ask 3 questions (if is in L1 and not in L2, if is not in L1 and in L2, if is in both).

See demo available on that matter.

Using code (the bad news) since the fastest Method available for "mapping" indices (via Point3dList) is not available as native component. This is critical for big number of points.

Using internalized demo points collections. Test it with big numbers to see the advantage.

Sorry: wrong question (for both) > wrong result.

Discard the V1.

thank you so much Peter :))

For BIG N of points this is the fasted stuff by some margin ... meaning discard V1A.

BTW: Do you speak C#? If so you can add more "query" questions.

Hi Peter

I am not really familiar with c#, so I think that your way is a bit hard for me, thank you for your help

Never mind - nobody's perfect.

Get a slightly faster version (minus one stupid bug)

Hi.

You can draw new lines per group by using Delaunay Edges connectivity data("C" Output)

Unlike your previous question, IMHO, what does it mean to make a code to find an answer to a question that has no reasonable standard of selection?

Just use the "list item".
