Cut Geometry selected by others

Hi!
My work involves creating structural components, specifically:
Steel columns embedded within concrete columns-SRC
Steel beams embedded within concrete beams-CES
After using Addins to Autojoin. Then objects of the same category have an unexpected join order.The steel columns and beams are largely cutting by the concrete columns and beams.

So, I tried using Dynamo to change this order again Steel Elements(List A) cut Concrete Elements(List B).

I am using Elements. CutGeometry to determine Joinorder for components of the same Category like this. However nothing changes after running. Is there any other node I should use to do this?
Thanks for any helps.

Your going to need to show a lot more detail before anyone is going to provide a response of any value to you.

Hi!
Forgive me if my explanation is not clear enough. I fixed it. Thanks
