The script works, but you should have your top and bot constraints set to a level and base/top offsets should be zero. Otherwise, the code does not work stable from my side. I think you need to modify the code if you want to use it for any conditions.

Hi @Amir.Moeini.Sh, Thanks for your response. I am running the above-shared script in Revit 2023. Per your suggestion, I keep the base and Top offset set to zero, and the top and base constraints imposed to a level. It shows an empty result.

Please take a look, and looking forward to hearing back from you.

Hi @manhgt214, Thanks for your response.
I used the above script, which is helpful for a single run for a single wall, but when I try to run on a closed fence, as mentioned below, it shows an error and deletes the selected partition. Please see attached images below for reference.

When I select the second wall.

Please suggest the solution for groups of walls at a single script run.

I ran the script on this model and it worked without error. (Revit 2023)

If the code does not work on your end based on the settings I mentioned, maybe something is wrong with your example model or Dynamo version issues.
