Here at Ideate we get a lot of questions on issues that arise in the workplace. Our topic de jour came up because ceiling hosted lights are deleted when a ceiling is deleted – meaning they would need to be placed again. Or, maybe no ceiling host object is available for a light, perhaps because a ceiling component is a face-based generic model, such as a specific custom tile. Other options would be to use a generic ceiling (zero thickness) or an in-place ceiling family. This option which originated in Revit MEP may be especially useful where models are linked. For example, linking an architectural model to a lighting model.

In this example you see how to draft and name the reference plane, and then place lights. Now, you'll be able to move the lights when needed and not worry about a hosting ceiling being deleted and remodeled with subsequent loss of attachments.
