Merge / Join result - Brep - Tree

[slavikvojtech]

Hi, I would like to know how can merge items properly . I know thats all about trees.

But still when I have same amount branches it’s not working how I would like to.

This is simple example I have BUILDING and I would like to merge with ROOF - like one building and keep it with possibility to choose final building trough Item list.

Please let me know what I should learn and where or some kick how it works.
Thank you

Where is roof ?

Do graft and simplify to the ROOF output brep parameter, so that first branch of SLABS output is merged with the first branch of ROOF, the second with the second, and so on, and use Tree Branch rather than List Item if your buildings is stored by branch.
