I am always using the "Hide All Types" command when modelling but I don't like how cosmetic threads are grouped in with it. I was looking into writing a macro that would toggle on and off the visibility of whatever I have shown, leaving the cosmetic threads always shown. To do this, I need to be able to store information on what is visible or not. I'm not sure what would be the best way to do this. I've come across IGet3rdPartyStorageStore but I don't know how I would go about using it. What would be the easiest way to temporarily store information on what was toggled on and off?
