An option is to create your floor structure as one floor and then place
another floor on top of that which is actually your floor finish. That
gives you stacked floors.
When you place a floor, Revit places that floor based on the very top of the
floor. If you have different floors with different finish material
thicknesses, the actual floor structure or sub-floor information may not
line up correctly if you are not careful.
For example, let's say that you have a 4" concrete floor slab, with some
areas having 1/2" carpet, some areas having 1/8" vinyl tile, and some areas
having exposed concrete. If you have the 4" concrete floor slab as its own
floor system and place it in your model, you will use the 1st level
elevation as the top of the concrete floor and put it thoughout your model.
You then have a floor type which is 1/2" carpet and place it where you
desire with the "floor" offset at +1/2" to put the carpet on top of the
concrete. You also have a floor type which is the 1/8" tile and you place
it where you desire with the "floor" offset at +1/8" to put the tile on top
of the concrete. The concrete slab is consistent across the building and
the finishes sit on top of the concrete.
If you use the above option, you can get material take-offs for the various
floor materials. If you do not need material take-offs, you can just use a
basic concrete floor and split the surface at different areas and use the
Paint function to paint the various areas with different materials simply
for visual purposes.
Which approach you use can depend upon your final needs.
I hope that helps.

Hi there could any one tell me how to separate floor finishes without
creating
different floors. As you will see on the attached drawing i would like to
have different floor finishes
on the same floor slab is this possible
Thanks
