I want to make my lights have the ability to offset from a sloped ceiling and automatically tilt to a vertical plane so they appear to hang with gravity. Right now they hang at a 90 angle to the ceilings. Families are face based. Basically it seems I need to lock objects in but allow the host face to tilt. This "technology" could eventually add the ability for me to put objects on most any angle of surface and have they annotations show up in plan. It didn't seem possible when I tried it so I'm looking for some help. Thanks!

Open your light family and under settings / categories & parameters and uncheck the always vertical box. Now reload the family - go to the appropriate view and rotate your light to vertical.

Thanks, but that is not an option for light fixtures. In any case, I would like the light to hang down automatically, no matter the ceiling angle. There is probably some data extraction and a formula involved here.

I appreciate your help, even though you are absolutely incorrect. At least as far as what I'm looking at on my screen.  Under Settings-Family Category and Parameters, there are only 3 parameters available for Light Fixtures. Light Source, Part Type and Shared. MEP09 is the software version I'm using. Thanks again.

Well, maybe something different in MEP - here is Architecture 2009. This is just a lighting fixture - ceiling based has the same GUI.

The difference is yours is a Ceiling Based light fixture. We are using linked architectural models, so everything has to be "face based" or it will not place on the surface. Thanks again!

NO - as I said, this is just a light fixture ...... ceiling based has the same GUI. BUT NOW WE KNOW THE REST OF THE STORY! You used a generic model (face based) template - not a lighting template. If you had given that information eariler, we could have saved a lot of time. Faced based generics may work best for what you are doing but you could have used just a light fixture and aligned it to surfaces.

Here's a ceiling fan that always stays vertical. It's "ceiling based", so make sure you have a ceiling system to attach it to. Hope it helps you. Dano

Get a family started, use the screen shot and formulas and see where that takes you. I would be happy to help trouble shoot or work on a family. Or sell it if you want it done for you. Nick

7 years later...
I wanted accent lights for landscape lighting, and from a youtube clip:
1. Created ceiling-based light from template (be sure to uncheck 'Always Vertical' - you can't do it later)
2. Placed light family on ceiling in new project and saved project.
3. Linked saved project into new, empty project.
4. Clicked 'Collaborate->Copy/Monitor->Select Link' and clicked the linked project.
5. Clicked 'Copy' then selected the ceiling light, then 'Finish'
6 The light is now in the empty project as a face-hosted light, anchored perpendicular to the host.
