Abstract
Based on the characteristic of Mechanical Drawing and incorporated with the practice of multi-media teaching, the models of teaching and exercises and the new commands of drawing the standard components and parts most in use have been developed using the graphical software AutoCAD and Visual LISP. The students' space imagination is effectively improved the drawing speed of assembly parts is increased.
