Is there a way to insert lighting when there is no ceiling. For example, mechanical rooms, electrical closets, etc... often have unfinished ceilings with lighting suspended from the slab or structure above. However, I cannot insert fixtures into these spaces without a ceiling. I could make it a Gyp ceiling since this won't show up as anything on the reflected ceiling plans, however, they still show up in section. Is there a way to designate a ceiling as unfinished, or does anyone know of a light fixture which does not need to be hosted in a ceiling?

If you are using a light fixture that is hosted by a ceiling, you will need a ceiling. You could "fake it" as you suggest by making a ceiling type that is very thin and sits directly below the structure. In section the linework would probably just hide the fake ceiling. This method however has some pitfalls when it comes to the Revit mantra of "model it like you build it". For instance if you explore an IFC export to constrcution estimating software your contractor will find the "fake" ceiling and assign a cost to it when in reality there is nothing to construct. It would be better to have light fixtures that are floor hosted for this type of representation since that reflects reality. There are some family template files for just such a purpose in the Revit Web Library. I'm not sure what the implications are of trying to cut and paste from a ceiling based light fixture to a floor, but you can give it a try. HTH Tom

I have been dealing with this very same issue today (trying to host a component inthe ceiling workset when the room ((restroom in this instance)) has no ceiling) and I am intrigues by the suggestion of using a component that is hosted by the floor. My previous attempts have resulted in nothing and the only things I have been able to come up with is to just "fudge" it and draw a 5/8" gyp bd soffit ceiling on in my workset, duplicating the 5/8" gyp bd that is attached to the underside of the roof structure. and then attach my pendant light fixtures and exhaust fans to my "fudged" ceiling.

I have dowloaded those Autodesk families and will examine and try them out...I will report back my progress and/or my lack of it. GOOD LUCK TO ME!!

The default basic ceiling - generic ... has no thickness.  This is meant to be used at the bottom of structure above when a "ceiling" is needed to host lights & other items.  It has no finish but it is a line in section & elevation.

I was dealing with a same issue today. I created a new family with using a template lighting fixture.rft (no host). Then copy paste a lighting fixture you have (the ceiling or wall hosted ones) to the lighting fixture.rft. Save this as a new family with a new name on it. In this way, your lighting is free from any host and can place anywhere. No fake wall or ceiling needed. Hope this helps.
