IFC wall

Hi everybody!
I ran into a problem with an IFC wall. These walls come from an IFC model deliverd to me by an architect. The problem with these walls is that they are ‘static’. I can’t change the properties of these walls.
My first thought was to let Dynamo create a new wall, based on the surfaces from the IFC wall.
I can see the faces from the selected wall but can’t get the node Wall.ByFace to work.
What am I doing wrong here?
test wall.rvt (4.9 MB)
IFC wall.dyn (10.4 KB)

Hint:
Wall.ByFace works when you create a Mass family,

Thanks Marcel,
I’ll try that this weekend. Thank for your reaction
I think I’ve solved my problem too, see below.
It was easier as I suspected :slight_smile:
