Find slab or roof from ceiling

Hi, I’m trying to find where the ceiling panels are hanging, slab or roof.
How do I find elements which doesn’t have any intersects? I want to get some fresh ideas.

Try the raybounce method.
You can find the nodes in the DataShapes Package.

Hi, @Marcel_Rijsmus
Thank you for your suggestion.
I tried those nodes from the DS and bimorph packages but couldn’t find any elements that I wanted.
I put midpoints of ceilings(boundingbox) into Points(origin) and other inputs folloing the link that you posted and it just found the ceilings. Did I put something wrong inputs?

Thanks, I found the way through the Raybounce node.
