I was working on a wall panel project and noticed that parts and assemblies were a great tool to layout my project so that I could auto populate schedules, elevations and plans. I find the Assemblies function in Revit extremely useful especial for creating such items as wall panels where intricate items like studs, tracks and bridging can be assembled and essentially isolated for easy use.
Although when I need to copy these assemblies Revit does not provide me the option to create an exact duplicate of this wall panel where if I make one change to that particular wall panel (which is used multiple times in my building) and make those changes throughout my building.
I would be nice if an option to create a native duplicate of an assembly so that way I don't have to go through each panel (that is exactly the same) and make the same change. Seems like tedious work that can be easily eliminated by providing this functionality.
