Filter all elements by Level

Developers

Hello,

i want to filter all placed elements by level…
…can i also get the elements which are not addressed to a level?

import clr
import sys 

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

all_levels = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Levels).WhereElementIsNotElementType().ToElements()
lvl_names = []

for l in all_levels:
	lvl_filter = ElementLevelFilter(l.Id)
	lvl_names.append(l.Name)
	
	elements_lvl = FilteredElementCollector(doc).WherePasses(lvl_filter).WhereElementIsNotElementType().ToElements()

OUT = all_levels,lvl_names, elements_lvl

at moment i get too less object…

Hi,
here is an example that should work with most elements
