Dears I was trying to split floors , and I got an error only for one floor (it should be splitted in 4 parts, but I got only one) all other floor are working well any idea? thank you [image] [C2]

It states that the curves you provide for that floor cannot be joined properly. Maybe they are self-intersecting or There are “holes” in the floor surface or One of the curve could potentially be joined with two other curves. Can you isolate those curves and show those?

I couldn’t isolate these curves the strange thing is that this operation is successful in other floors [image]

@khalil.noureddine …you could try to group your curves…probably it could help you… [group]

I can now isolate the floor inner curves from the floor boundary the sublist 0 ,1, 2 are for the openings in floor but the problem is that i cant create this floor @sovitek @Joelmick [image]

You can isolate them. [000139] can you try to do this in your graph, this will give you the curves with cannot be used to create a floor?

You are still feeding all the PerimeterCurves to the floor creating node. You need to pick the curves you need from Group.Curves nodes and THEN feed them into Floor.ByOutlineTypeandLevel

Difficult to say, you need to share the files…but why dont you not feed in the grouped curves

Dears, Sharing the files @sovitek @Joelmick @filip.kabelis @ test.rvt (1.4 MB) Split-Floors.dyn (80.2 KB)

Aah I am analysing your files. I see the problem. You are trying to make floors with holes in them. Dynamo cannot do that to my knowledge. You can create Floor opening Elements with Dynamo. What you can do is split the Curves of the surfaces in curves for the outline of the floor and the curves for…
