I agree 1000% !! Also when you shut off the pipe in Visibilty Graphics the Insulation should dissappear also. Can someone tell me one reason why you would leave the insulation & shut the piping off. These should go hand in hand.
Sorry, but I had to add to my RANT! Why does my insulation always go back to 2" thick? I place a pipe & change the insulation to ... say 1.5" & when I add the insulation it defaults to 2". Everytime now I add the insulation I keep everything selected & edit it to whatever size I need. It would be fine with me if you could just pick 1 size & use it for everything. Obviously best case would be to assign different thicknesses to filters for different pipes EX. Chilled 2" Hot 1.5".
