The axonometric projection in mechanical drawing

Axonometric projection is closely allied to view layout and projective transformation in CG. In the published books of mechanical drawing, there are few of the forming method about axonometric projection. This paper analyses the forming method by 3D graphic projective transformation in CG. The characteristics of generality about axonometric projection are presented, as well as the special axonometric projection drawing, that can strengthen the theory of projection and axonometric projection. It proved to be good result to the teaching practice.
