Datas list organisation - Get walls for each rooms

Revit
1

Hi everybody!
I would like to obtain walls for each room but i have some issues to merge datas together especially because i have more walls datas than rooms… and i need to identify the right room with the right walls… I’m not happy with the result i got with the list.combine note because i have the area attach to the wall type in the same row.
Does anyone have an idea to merge room name with area and walls type i obtain with room.boundaries node?
Sincerely,

datas_organization

Hi @r.machicot,

The result you want in excel isn’t very clear but here is an example :

Thank you Alban, that’s exactly what i wanted to do. I learnt a lot with your script but i obtain more walls than i have in real. I think it comes from the list.takeitems node and the count one.
For example, room.boundaries node got me 8 walls and 1 floor (for the first room) then list.takeitems node count 57 items for the first room, identified as nul.
Do you know why? Did i use list.takeitems in a wrong way?

Hi Romain,

You’re right. My test file wasn’t appropriate.
For a real project, you have to set on longest the lacings of the Count and List.TakeItems nodes.

is it now possible to combine the same wall types and calculate the total wall area by room?
