We are a multi-discipline firm where our typical Revit work flow is that each discipline has a central file (Arch, Elec, Mech/Plumb, Structural) and then we would link each other disciplines model into your own (i.e. me as an architect would link in electrical’s Revit file.) When it comes to RCP’s we link in the electrical light fixtures and would like for it to cut the 2’x2’ ceiling grid where we have 2x4 lights. See attached image.

I tried masking regions with no luck. Any help would be appreciated.

One step further…is it possible to constrain the light fixtures to our gird, such that if we (architects) move the grid then the light fixtures (in the electrical file) would move with the grid adjustment. Copy/Monitor function here maybe? Somehow?

Sorry - Hosted objects can only cut their host.

Read the many posts on this subject and you may find an acceptable answer.  See similar threads below.

 I have looked at similar posts, all address the situation, but none solve it or really propose a solution. Any other ideas?

I have not used copy monitor a lot but from the help it seems like it would be your answer

i know im a little late to the discussion....

What I have done is create a Detail Item family that I place in the Light fixture family. In the detail item family I have symbolic lines, 2 filled regions (for the emergency fill) and a masking region (for non-emergency). I set 2 new parameters for Emergency and Non-Emergency so they can be turned on or off as needed when the family is placed.

It doesn't seem to mask the ceiling grids in the electrical file (not sure why), but my electrical guys only use the grid for placement and then turn it off anyway. When the Electrical model is linked into the Arch file though, the Elec lights do hide the ceiling grid in the Arch file.

I have attached a sample Recessed Light Fixture for your use or reengineer.
