Hi All, This topic seems to be unresolved as far as I have found. So, the basics are that I'm working in Revit Architecture 2009 and am having problems lighting up a residential room with recessed cans. As it stands now, the light from the recessed cans is being blocked by both the structural floor joists and the gypsum board finish. One way I can get light to radiate is to turn both joists and gypsum board to glass, but that means that the can becomes visible as well (floating in the ceiling). I would have thought that the light-can would automatically create a void in the floor system to permit the inner workings of the light. Based on this notion, I tried creating a void the exact size of the can inside the rfa family to see if that would do the trick in the floor system but that didn't work. The other way, which feels unrealistic, is to lower the light source so that it is at the surface of the gypsum board. This second method is more in line with flush surface mounted fixtures and less desireable. It sounds like this problem is exclusive to 2009. Attached is a draft. Would anyone care to share a work around? Thanks.

it sounds like that you have structural floors and ceilings. if you have the light in the ceiling and the light source is inside the structural floor that im guessing it is blocking it. can you simply turn the structural floors off in the view?

There is a problem with the recessed cans in 2009, but this has been rectified in 2010. In 2009 you need to edit the family and lower the light source slightly. It should then work.

Not quite sure what having "structural floors and ceilings" has to do with it, maybe 2009 gets confused with lights inside structure? Anyway, lunchtrayrider's suggestion to select the joists in the view port just before rendering and "Hide in view" worked out! By Hiding the structural floor, why isn't the gypsum board hidded as well? Wouldn't I be staring at the second floor ceiling? Attached is the final image. Thanks to all.
