Finish floors have always been a problem for me. I want them turned on in certain views and off in others. Here is how to do it. Its fast and easy.

From the menu, go Settings/Object Styles.
Make a new subcategory under floors. Call it 'FinishFloor' or whatever works for you.

Now in a plan view make an in-place floor family.
extrude it from the top of level 1 for example up 1/8" of an inch or so.
Under properties set the subcategory of the family to 'FinishFloor'. Set the material, finish the family and presto! you have it.

You can now turn it off separately from your other floors using the standard view settings.
