import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import FilteredElementCollector,BuiltInCategory
clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager

doc = DocumentManager.Instance.CurrentDBDocument

levels = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Levels).WhereElementIsNotElementType().ToElements()

chop = []
n = 0
m = 1

for i in range(len(levels)-1):
	chop.append([levels[n],levels[m]])
	n+=1
	m+=1

start = []
end = []

for i in chop:
    start.append(i[0])
    end.append(i[1])

OUT = start,end

The script works, but you should have your top and bot constraints set to a level and base/top offsets should be zero. Otherwise, the code does not work stable from my side. I think you need to modify the code if you want to use it for any conditions.

Hi @Amir.Moeini.Sh, Thanks for your response. I am running the above-shared script in Revit 2023. Per your suggestion, I keep the base and Top offset set to zero, and the top and base constraints imposed to a level. It shows an empty result.

Hi @manhgt214, Thanks for your response.
I used the above script, which is helpful for a single run for a single wall, but when I try to run on a closed fence, as mentioned below, it shows an error and deletes the selected partition. Please see attached images below for reference.

Please suggest the solution for groups of walls at a single script run.

I ran the script on this model and it worked without error. (Revit 2023)

If the code does not work on your end based on the settings I mentioned, maybe something is wrong with your example model or Dynamo version issues.
