i try to make a list with the elevation level parameter for all elements in my project.
I use “Element.Level” to obtain the level of my element and then i try to extract the “elevation” parameter.
so i try to flat my list, it works, but dynamo delete all empty list
i need the empty list because i have to associate the “elevation” parameter whit the “ID” element!
How can i do?
