Old python (2.7) script for dimensioning does not work in Cpython

My old python script does not work anymore in the new version of dynamo where it uses Cpython.
I have a script that added a dimension to selected grids and columns.

I get an error that I have to use “Autodesk.Revit.Creation.ItemFactoryBase.NewDimension”. I first had “doc.Create.NewDimension”. After I did that it says that no method matches give argument for NewDimension. What kind of input does it want, I checked the Revit API but that one hasn’t changed.
Do some of you have the same problem?
Is there a website that says how to write code in Cpython for dynamo?

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

import Autodesk

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

references = UnwrapElement(IN[0])
line = UnwrapElement(IN[1])
elementlist = ReferenceArray()
dimtype = UnwrapElement(IN[2])


for ref in references:
        elementlist.Append(ref)

TransactionManager.Instance.EnsureInTransaction(doc)

dimension = Autodesk.Revit.Creation.ItemFactoryBase.NewDimension(doc.ActiveView,line,elementlist, dimtype[0])

TransactionManager.Instance.TransactionTaskDone()

OUT = dimension

Hi @Lunzur

You can run your script in Ironpython. But they removed Ironpython from the latest version of Dynamo OOTB. You can install it via the package manager. Search Ironpython and there is a package from the DynamoTeam. After installing that, you can set the Python version on the Python node to Ironpython.
