Is it possible to put lights without hosting it

Anonymous — Fri, 23 Jun 2017 05:15:48 GMT

Hello,

I have received a project from a consultant and the file does not have ceiling on it. Creating ceiling could be risky because it might have some bulkheads or other stuff on it. I was wondering if I could put the lights without hosting it . If there is any option to specify the mounting height for the lights. ANy idea please?

You don't need to create ceilings. Use lighting fixture families in Lighting\MEP folder, they are face based families so you can place them directly on any surface of the link model. When placing, look at the Ribbon to pick Vertical, Horizontal, or work plane.

To add to @ToanDN, in the OOTB library, there is also a studio light.rfa which is only a light source and it’s a level based family. Giving an offset from level, you could place it anywhere.

Another option is to create a new Level for a floor's lighting fixtures, open a plan view (or RCP if you prefer, and depending on which way the fixtures are modeled) of that level, and host them right onto the Level. I do it all the time.

Use non-hosted families and assign the elevation.

Hello,

The best workflow is to create a ceiling level and host the lighting fixtures on it because if you don't host them on a level you can't change their elevation in one step which may occur at any moment by the architect .

If my answer helped you , please kudo and accept as a solution.

Thanks

Not as the question was stated.

"I was wondering if I could put the lights without hosting it . If there is any option to specify the mounting height for the lights."

Remember also that there is no best workflow because people work in different ways. For example, I would avoid using levels as a lot of my projects have multiple ceiling heights in different areas. Levels are much harder to control that workplanes, which, IMHO, are a much better option, if you want to use hosted families.

Hello,

I know what the question was but it will cost him much time so the hosting level is a good solution for lighting fixture but it isn't a good workflow if you

place air terminals for example.

The workflow i suggest is working very well in my project with almost 13000 lighting fixtures.

If my answer solved your problem , Please Kudo and Accept as solution.

Thanks

Just because it works well for you, doesn't mean it is the best for others. There are plenty of places that don't use hosted families for anything.

Hello,

It is up to the man with that problem to decide whether to use it or not.

You are a tough nut to crack. Think outside of the box.

Any family that DOES have the ability specify an offset (or mounting height) has to - logically - know its offset FROM something.

This usually means its a family that is hosted to a Level. You use a fixture that is hosted to a Level and then you can set the offset for each instance as you desire.

Maybe you are not a good nut cracker,look at the bigger picture and try to extract knowledge and don't bother by unimportant details.

Is it possible to put mounting height as a parameter and not using the vertical, horizontal or work plane option?

Great!! so does it mean that I can host to the floor and then give the mounting height as the offset?

How do I know which one is non-hosted lighting fixture? Can I create one? Or duplicate the properties and assign the constraints?

I'm fairly certain that all of the lighting fixtures that come with Revit are hosted. You would have to find some from a trusted source or make your own.

It means that you can place "On a Work Plane" (that is a Level) and give the mounting height as the offset.

Key words there because work planes are much more versatile and easier to control than levels.

Sure, but the OP is looking for a way to set offset above a floor. In this case, using a Level as the work plane (which is the default condition unless you set a different plane as the workplane first) is perfect.
