Hi there, my apologies, I’m a beginner and my question may sound silly.
I need to filter wall elements in a whole Revit project and sort them by level, by height and constraints before editing them.
Therefore, I used:
Categories (wall), All Elements of categories, Parameter by Name for 3 or more parameter names. I tried to combine the data with List.Combine but the result is empty.
Do you know where may be my mistake ? Thank your very much by advance.
