cut lines above recessed light fixture in ceiling

Hi, can anyone tell me why these lines are showing up above my pot lights? The lines are part of ceiling (if I turn ceiling off they go away).

It's like Revit thinks the pot light cuts through the whole ceiling.

This is a wireframe section view.

 

My family based on the stock recessed can light out of Revit 2016

 

thanks!

Is your ceiling a solid object, full height thickness? The opening cut in the family always cuts the full thickness of the host. In the family, delete the opening and use void extrusion instead. Lock its height to the height of the light.

Good catch Pij! I was trying to figure out what I was looking at when you posted. You're right on the money! That's got be it. The ceiling is a solid and the opening cut is penetrating the extents of it.

I might be right on the money, but the real question is: is this ceiling really going to be constructed that way? I’d say unlikely, so instead of messing with the light family, maybe the ceiling should be revised.

It is a soffit.  It's easier to model it as one thick piece instead of a thin ceiling with short vertical walls around, I guess.

okay, thanks. That is probably the case. I'll let the designer deal with it (I'm electrical and adding light fixtures to her model). I think we will just let it go.

I don't model soffits as thick slab constructs extruded downward from underside of a ceiling. By definition, a soffit is dropped ceiling, so I do just that: I create an actual compound layer ceiling type ("Soffit") and place it on the appropriate ref. level or plane. Most do it that way, Toan. Even back in the days of hand-drafting, we were drawing soffits to scale.
