Hi Hatwig, I can't really work out what you are after from your email, but in terms of different coordinates systems, do you mean different coordinate frames, or totally different types of coordinate system such as polar? Different coordinate frames can be done simply by placing a MatrixTransform/PositionAttitudeTransform above the subgraph that is in the dfferrent coordinate frame. As for totally different types of coordinate systems then you'll need to be specific, we can't guess what's inside your head.
