Is isometric drawing 2D or 3D?

An isometric drawing is a 3D representation of an object, room, building or design on a 2D surface. One of the defining characteristics of an isometric drawing, compared to other types of 3D representation, is that the final image is not distorted. This is due to the fact that the foreshortening of the axes is equal.
