Ok so I am having a very difficult time with revit systems. If I change one little thing it will tell me that the system is not properly connected, or just this last time that my fittings dont have loss associated with them?? what gives? Dont they all come from the same table? As far as I can tell I drag the pieces so I get the little pink cross hairs, and the system gets put together, so I can tab select the entire system so why is it coming in as not connected? this is so frustrating! Does this mean that I can't ever change out a single fitting? where does it end? I changed out a single fitting, and now I cant use my system inspector?? Please help!
