Hi @rgoski329

You need to start a Transaction as well as ending it :slight_smile:

I see now that you are trying to call a node, and not an API call. I don’t know if you can access the nodes like that :slight_smile: .

The API call to create a new level is this one: Link

if you want to use a DynamoRevit method, it’s necessary to wrapp your Revit API object

import clr
import sys
clr.AddReference('ProtoGeometry')
clr.AddReference("RevitNodes")
clr.AddReference("RevitAPI")


import Autodesk
from Autodesk.DesignScript.Geometry import *
# Import RevitNodes
import Revit
clr.AddReference('RevitServices')
clr.ImportExtensions(Revit.GeometryConversion)
from Revit import GeometryConversion
# Import Revit elements
from Revit.Elements import *
clr.ImportExtensions(Revit.Elements)
# Import DocumentManager
from Autodesk.Revit.DB import *
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
from Autodesk.DesignScript.Geometry import *

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication
app = uiapp.Application
# The inputs to this node will be stored as a list in the IN variables.
levels = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Levels).WhereElementIsNotElementType().ToElements()
# wrapp the level
lvl = levels[7].ToDSType(True)

Revit.Elements.Level.ByLevelOffsetAndName(lvl,12,"New Level")
TransactionManager.Instance.TransactionTaskDone()
# Assign your output to the OUT variable.
OUT = levels
