I reckon it has been talked about many times before - but is there any other way to extract this fairly simple floor geometry in dynamo?
With Element.Solid I get the exact same error
Element.Faces could also help. And there is always “select Faces” if that to fails.
Was this geometry cut by another solid? If so try removing the cut geometry and see if you can pull them in separately.
Seems that issue occurs when revit OOTB openings - By Face are used which was the case with this floor.
When revit OOTB Opening Vertical is used then nodes work correctly.
