Hi I am trying to create floor from lines. It is working fine but each polycurves creating separate floors. I need all polycuves to be single polycurve which should create a single floor. [image]

Typically the reason why this node doesn’t work for people is the list structure it expects. The curvelists input requires a list of list of lists of curves. I’m using Python and a predictable list input here so the structure is critical, I’ve built it to receive a list of finish boundaries from a l…

Could you show your lines and also the drop down from the Surface.PerimeterCurves node?

See there are four rectangular polycurves. When drop these polycurves to Floor.ByOutlineTypeAndLevel it is creating floors for each rectangular curves as separate. But I need all blocks to be in a single Floor or Element for that polycurves must be single object. Correct me if I wrong. [image]

If you’re in 2022, maybe you can use one of the Crumple nodes: [image]

Hi @jostein_olsen the above node not working.

is there other methods if I am not using Revit 2022?

Floors with openings. Take the polycurve from the room which has the largest enclosed area, then put the others into separate lists to make as openings. It wont be like a sketch though unfortunately. Springs package has some nodes which can make floor/wall openings. That or time to upgrade …

Hi @GavinNicholls FloorsByCurveLoops is working fine. Since it is creating separate floors for each room. Any suggestions to get single floor(single element) for Room 1 and 3. Thanks [image]

Room 1 and 3 are two different rooms, so no I can’t see a way to generate them as one room unless you combine their boundary curves. Revit/Dynamo don’t really have a way to identify when that scenario should occur though so you’d need to program the logic of adding those curves together yourself.

In my case I’m not using rooms only model lines.

If you are in Revit 2022, make a single floor of any one of the shapes and edit the sketch to produce the desired result with the graph here: Sketch Lines - Edit, Copy, Paste - #20 by jacob.small
