Thank you for your quick responses. Floor material won"t be transparent originally. Right and left floors will be the same material(concrete etc.).
However, one of both Floors need to be transparented in the 3D View as well as plan view.We are not planning to demolish.
There is no any special reason.Only, I am planning to use it for representational reasons
I hereby attached rvt my rvt file for your reference.
when i assign a transparent material to the desired floor, the second floor is also becoming transparent.
I tried to set it transparent but nothing was there. please check below photo.
We remain,
