I don’t quite understand what you are asking. The world coordinates cannot be changed, they form the basis of the 3D environment. And as I wrote, “2D” generally is everything with worldZ=0. Hence Make2D creates your view of the 3D model (the current view or a projection on one of the viewport CPlanes) onto the wordldZ=0 plane. @Rajaa is now polling to see if there would be support to add an option for a different target plane, but that would be a future enhancement.
Moving/rotating any CPlane is possible, that would have an influence on the resulting picture when you select that CPlane as the projection plane, but the result will still end up on the 2D plane, i.e. the Top View default CPlane.
