When we create different Display States, can we show or hide parts based on the Property Name (its in Summary Information/Custom)? The reason I am asking this is we create all parts with numbers like 48556, 47852 etc. When we want to select or hide some parts (like all valves in an assembly, say 50 pieces), its tedious to identify/select all valves, small or big. But if I am able to create a custom property name Item Type, and designate the Item Type as Valve, it will be easy to select and hide it in a Display State. Any advice please? Thanks in advance.
