linked model not masking Ceiling

[andypowell32578]

I have a problem. The linked model from our electrical engineer its lights are at the correct height but the ACT ceiling is still running its lines throiugh the lights. how do we take care of this to where the linked model which has the lights in it cut through our ACT ceiling from our central model?

The issue is the linked file is not actually 'cutting' the ceiling - it is basically overlaid so that is why you are getting what you are getting. To get the ceiling to cut - you can do a copy/monitor the lights into your file.

LD,

I can't, for the life of me get Revit to allow me to copy/monitor light fixtures.  BUT I keep reading about people recommending it.  How?? 

Thanks!
