In Tube & Pipe, sometimes you have a run that is built fitting to fitting with no actual route involved. See the example in the picture, it is made up entirely of pipe nipples and fitings... quite common in the real world of piping. If, however, you need to make a change in the middle of one of these runs, you have to break all of the connections downstream of that change, and basically redo the entire line. For some reason, T&P wants to recalculate (and often change) the rotation of each fitting, and so requires that the connections be broken first.
My Idea... is to fix this. In my example line, the regulator needed to be pulled out of the line and reconnected facing the other way. Simply rotating it 180 degrees won't work because then it would be upside down. In order to accomplish this, all of the downstream connections between tees and nipples had to be deleted and reconnected. A lot of work for a simple change.
