Issue with intersecting two sloped floors

Hi everyone,

I have a problem with cutting the two sloped slabs. Basically, I want to cut the green slab (upper one) by the orange slab (lower one). I tried Element.CutGeometry but it does not work.


Please share any advice or help. Thanks (attached rvt file for ref)

Hi, @Brian.Tran
Can you do it just in revit? Maybe geometry is bad.

Thank you @sovitek. Your solution works well. I checked the slopes at the bottom of the cut slab and it matched with the slopes at the top of the lower slab. Creating a void family for cutting from the model element is a good idea.
