Re: Copy lighting fixture
Jesse,
Unfortunately, OOTB Revit does not support the function of copying a circuited lighting fixture, and adding the new fixture to an existing circuit. The closest Revit is to that is the 'CS' (Create Similar) command. This should copy in a fixture of almost identical data (Offset, VA, Ø-Phase...etc..). But the workflow of adding it to a panel is on the drafter.
There are Revit Add-Ins that may have that functionality enabled, but my personal preference is to add them to a panel myself.
