Improvement on creating axonometric drawing and (two-)dimensional projection from three-dimensional model in AutoCAD

An improvement has been carried out on the generation method of 2D engineering drawing from 3D model in AutoCAD, and formed an intact methodology and skill of generating axonometric drawing and multi-planed orthogonal projection drawing from 3D model. This kind of method is a suitable method for obtaining the axonometric drawing and orthogonal projection drawing that could be compiled more conveniently into various forms, thus this is a method suitable for implementation.
