Topology.Faces error

Could someone help met out with this node error? It seems like it doesn’t matter what I connect to this node (select model element, all elements of type, wall types etc.) I always seem to get an error and a null value.

Hi @selim.celem

Error says you can’t feed Wall (Revit.Elements.Walls) as it is expecting Geometry like Surfaces, Polysurface and Solid as “Topology” input. You can use “Element.Faces” node after “All.ElementsOfType+” to get surfaces and then connect to Topology.Faces node.


Yep, I’m stupid. Works like a charm. Thank you!
