So, @john_pierson, your solution works…but not with linked files. Is there a way to do the same thing but read the ceiling from a linked revit model?
UPDATE: I actually got it to work through the “get elements from link” node. It doesn’t work on links just by itself. Sorry, it’s dynamo amateur hour over here lol
UPDATE 2: After a few more tests, it doesn’t seem to pick up that the centroid of the linked ceiling is in my space. I have added the bounding box nodes to spaces in order to visually verify that the ceilings and spaces DO intersect. It seems as though that they meet each other, but don’t actually intersect.
