I read a 2009/10 thread, "Rotating lighting", describing how to work around the problem of family lighting fixture members not rotating. I would hope there is a better solution today.
I simply want to place a lighting fixture - std 2x4 flourescent, on a 7 deg sloped ceiling. The axis of rotation is the long run of the light fixture. Is this not possible in Revit 2013?
Or, do I have to dredge up the work around from 3 releases ago and attempt to discern how to make it work?
It seems like I should just be able to set the family to use a work plane-based assignment and then place it with the correct work plane active. That is not happening. The light fixture doesn't want to rotate the 7 degrees to align with the work plane.

You will probably need to use a face-based light fixture family. The standard flor. fixture is ceiling-hosted, and may not work correctly on a sloped ceiling?
Thanks for that helpful bit of information; it makes sense.
Being somewhat of a Revit novice, does that mean I have to create a new faced based version, or does Revit have such in its library?
Guess I need to study up on the Revit family thing.
Then, my only conclusion is that the family object and I use different terms and concepts for relating to a plane because when I select the plane for the object to go on it gets offset (apparently a feature of the family) and is parallel with the floor regardless of the fact that I have the sloped reference plane selected.
I imagine that it is my lack of familiarity with families that is causing me this issue. Nonetheless, one would expect this to be more straightforward.
Thanks for the feedback and advice.
In the family Properties, see if "always vertical" is checked. and also "work plane based".
If so, uncheck "always vertical" and see if it will behave correctly on a sloped ceiling.
It might be something in the family that you are using. Please try with "Ceiling light - linear box.rfa". This family is ceiling-based, and it can be placed on a sloped ceiling.
Another good option is, if possible, is to use families from the MEP folder of the Lighting fixtures folder in the library (If you have that folder, of course). It is available in Revit MEP or in Revit 2013 One Box. Those fixtures are face-based, and are basically the same fixtures, but with a different kind of host.
Attached is the definition I have...

Perhaps my error is selecting a workplane instead of the ceiling when placing it. However, if I attempt to place it on a face, I get an error and a request to save everything into a recovery file.
Thanks... that last piece did the trick!! I very much appreciate the responses and assistance and if ever I can return the favor I shall.
