Try the command "UCS" it gives you several options to use reference planes. For example "view" makes your current view your reference plane and with "face" you can select a surface of a 3D body to use as reference. And there are more options (you will have to try yourself which suits your needs best), using "UCS" -> "World" will return your default settings after you are finished.
