import clr

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc =  DocumentManager.Instance.CurrentDBDocument

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

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

elems = UnwrapElement(IN[0])

TransactionManager.Instance.EnsureInTransaction(doc)

TransactionManager.Instance.TransactionTaskDone()

OUT = elems

hi，It can be achieved with IronPython, but with Cpython it still doesn’t report an error, showing “NameErrer”.

@Dongzi it is working from my side with CPython3; Can you share your DYN file?

@Dongzi your file is working from my side as well, I think you need to install Python 3. on your machine.

I installed Python 3.8.3, and everything else runs normally. Excuse me, is your Dynamo version up to date? Revit2022 version used?

10

I am using Revit 2022 Dynamo 2.12.0

11

I am using Revit2021, and then upgraded Dynamo to 2.10, will it be the reason for my upgrade.I’m using the cracked version. . The original is too expensive. . . .

hello @Dongzi
any reference to cracked software versions is prohibited on this forum.
CPython3 engine is not available before Revit 2022, this topic will be closed
Note:
if you are a student, try to apply for an educational license of Revit :slight_smile:
