Thank you for your answer. I used the built-in version of Revit to open the program. What else must be added to this version? Because I haven’t used it before, please give guidance if you need to add anything, thank you ---

Actually in Revit 2020 you can install “Monocle” package you can check which nodes (packages are missing). In your pic you use a python-script, whats the error, you can open it via douple click and post the code to the forum. KR Andreas ---
