I am an architect and linked mep to my revit file
we have "exhaust fans" and "Packaged Water Chillers"
now,I want to hide all "exhaust fan" in roof plan,
-if I unmark the mechanical equipment in V/G , all of them...hide
-I can not say to mep team to specify a workset for "exhaust fans"
-and it is impossible to select one by one with tab and hide them
Thanks to show me the best way
