I would like a property for all engineering items to mirror them after they have been inserted into a drawing. When you place a 3-way valve on a vertical pipe for example it puts the middle port to the right. I want to be able to mirror this item so that the middle port can be shown going to the left. This doesn't affect the flow at all as it just allows the user to be able to mirror an object so that it can have the port going left/right or up/down on the middle of the valve. It would also tell it that the actuator on a control valve with a 3-way body would be up/down or left/right. It would make things so much easier to deal with as I wouldn't have to be constantly flipping/rotating/mirroring my 3-way valves and objects like that because as soon as I move the valve on the pipe or move the pipe it changes my valve back to the default which causes me to go back and redraw everything that I have changed.
