I have a very long list of elements, consisting of walls and model curves.
Within the wall category I need to isolate all the curtain walls while maintaining the list structure. The list structure has 143 sub-lists, which I need to keep in tact as I am trying to find the curtain walls that are in each space specifically. So far I have fed the information through to the Element.Name node, then to WallType.ByName, then filtered this list using the string.contains node to get a list of only the curtain walls in each space.
So I have the arrangement I need, but my problem is that every one of the curtain walls has the same Element ID in the list, so it doesn’t look like it is the Actual Revit wall and I cannot pull parameter from them. Can anyone help me with this?
