Merging and splitting lists

[ZTrick]

Found it by myself:

Split list of coordinates into several branches

Wow thanks, can’t believe I missed it ! Partition is better than Path mapper in my definition, because the number is subject to change due to precedent parameter, thanks a lot ! And, while I’m at it, what would be the best way to retrieve one branch of the tree ? (with all 4 coordinates) Basically I need the list item for subset, but the “Sub list” component isn’t working, how should i input the domain properly to get those points ? 171220_demo_GH_v2.gh (15.5 KB)
