i needed to cut a whole in the floor above because im using recessed can lights and i couldnt get the lights to not be "embedded" into the floor above and im rendering from a point where you can tell if the ceiling doestnt hit the floor above. Do you have any other suggestions??? if so that would very helpful

A real model will match the real world ... If you want to use these lights (which I assume are correct) then in the real world, you would need either a lower ceiling or a greater floor to floor. Your other option - real world - is different lights that will fit in your ceiling space.

I have had this problem, and solved it as follows: I have recessed lights placed in a ceiling. It's a sheetrock ceiling, below a stock Revit 10" joist floor above. The recessed cans are placed in the ceiling and cut it, but they don't cut the floor above, so that the light source, which is 3" up into the can, is above the bottom surface of the floor, and therefore don't illuminate anything. In the model view, and in the rendering view, you can see that the bottom of the floor slices through the recessed can. If I temporarily hide the floor above, I can now see up into the cylinder of the can, and I can render the scene just fine, with the lights working. I prefer to leave the floor defined as is, because it reflects what's going on structurally. But I don't like the rendering effects. So I've edited the floor family structure so that the "structural" joist layer renders transparently, with index of refraction of air. The lights then work just fine. It's not ideal, but I don't have any ill effects in my models from this - I don't have any situations where the joist structure (which is anyway modeled in the stock Revit family as a solid layer of wood) needs to be rendered. If I did, I'd use something other than the stock Revit family anyway. I believe that this is a fairly common source of this fairly common problem. It's easy to investigate, by temporarily hiding items (floors and roofs above) and seeing how rendering is affected. By the way, wire frame makes it easier to find, hide, and eventually unhide the offending objects. I would avoid manually cutting holes in roofs and floors above, to solve the problem. That's just asking for problems later, as you move lights around, and as you use revisions - very easy to lose track and get a confusing mess. Commercial folks, who are dealing with concrete slabs and dropped ceilings, and plenty of space for recessed cans, are pretty unlikely ever to run into this problem. The references that I have seen seem to be single-family home, which is where I ran into it, where the cans are recessed not only into the ceiling but into the floor above also. Hope that makes sense.
