I want input finish wall in Dyanmo.
But I couldnât edit code in Python.
Could you tell me?

I cant find wall finish by room bond - please help me to find it
Modelical Try.dyn (6.9 KB)
I have tried the Modelical Node in 2019v Revit and 2.0.3 Dynamo, it returning null in output and nothing is creating. Can you help me on this Please?Wall Finish Pro.rvt (1.6 MB)
Thanks
I have a similar issue, I want to run the node but I canât because the node has an error. Iâm new with Dynamo, if someone knows what happen please let me know.
change Rooms to rooms as a start. The message on that node should make that fairly clear.
I tried it and the message disappeared but itâs still not working. It makes ânullâ when I run it. Itâs weird beacuse in my old computer I used the same routine and nothing happended until now.
Copy the Python node into the main workspace, and run that on a single item. The node should provide some direction in terms of why it is failing.
I did and nothing happen, watching other blogs I noticed the âRoomsâ is a class name and I can´t change it as a variable. The problem is, when I change something like âroomâ in the node, it doesnât work and I donât use python to change the script or something to fix it. If you know what can I do please let me know.
After copying the python into the main Dynamo workspace (not the custom node), what was the error message when you passed a single room into the first input in the Python node, a string for the Wall Finish Parameter name into the 2nd, and a string for the Ceiling Height Parameter name into the 3rd?
Can you help me to solve this. It is working in 2019v Revit and Dynamo 2.0, but the error caused in Revit 2022 and Dynamo 2.10
I am not good at python 
This is the unit type change associated to the forge type ID.
@Konrad_K_Sobon did a good job highlighting some of that here: https://archi-lab.net/handling-the-revit-2022-unit-changes/.
There is also some good summary discussion on this building coder post from @jeremytammik: The Building Coder: PDF Export, ForgeTypeId and Multi-Target Add-In
And finally, there is the API documentation includes the new class here: ForgeTypeId Class
This isnât intended to be a âfixâ, but more giving you the opportunity to fix the issue yourself first - itâs not super easy, but itâs also not so difficult to do that you shouldnât be able to make some headway and get better with Python. Should you give it a shot and still be stuck, post the DYN and a really small sample Revit model and the larger community will likely help out.

Hi, I have checked the post by @Konrad_K_Sobon and @jeremytammik It was interesting and very informative.
But due to my lack of expertise in Revit API and Python I cant fix the issue.
So I am posting a sample project and Dynamo file as said by @jacob.small
Actually this script is coming from Modelical Package.
In model there is a Room placed and Wall Finish type inputted in Wall Finish Parameter and Height inputted in Ceiling height parameter and while running there is an error regarding âUnitTypeâ
I hope updating docLengthUnit = Document.GetUnits(doc).GetFormatOptions(UnitType.UT_Length).DisplayUnits this line may fix with new way of fetching the Display unit.
Anybody can help, Thanks in Advance
You need to provide valid inputs into the Python node. Currently you are just passing a function.
This node doesnât work in revit 2022
yes this node not working in revit 2022
