Hello! New Dynamo user here. I took the existing code from here ([Dividing parts with dynamo - #36 by JacobSmall](https://forum.dynamobim.com/t/dividing-parts-with-dynamo/5388/36)) and modified it a bit to suit my needs. The problem I’m running into now is that I need to select an existing Part instead of an existing Wall. I changed the dynamo part of it to do what I need, but I’m getting stuck on what to do with the Python Script.
It keeps giving me the error:
“Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):
File “”, line 23, in
TypeError: iteration over non-sequence of type NoneType”
I know it has something to do with the script calling for a wall but I’m not sure where the edits need to take place. I can get the lines to divide the parts where I need but it fails dividing it.
here is the .dyn:

Any help would be appreciated! Thanks.

I have not! Deadlines came up and I had to stop working on it but I would still like to resolve it

> Hello, I am experimenting with diving walls into parts using the amazing script create by Einar on this post: The problem is, after a successful run of the scrip, Revit does not regenerate its view, so I can’t see or interact with the created parts using Revit. [image] But if I manually create parts from another element, it immediately updates the previous elements and then I can see the parts.
