Abstract: During the teaching reforms and practice of CADengineering drawing and computer drawing, we exploratorily applied typical graphic symbols to combine the illustration and hands-on operations, integratingthe graphic legend with CAD commands dynamically. Through the introduction of the drawing process of hand type figure, this article demonstrated a variety ofapplications and skills of circle drawing using AutoCAD software. The comparison between circledrawing commands in the tool bar and those in the drop-downmenu revealed more useful functions listed in the dropdown menu. This teaching approach facilitates the mastering of CAD drawing methods and skills, booststhe students learning initiatives and practical abilities, and promotes the quality of both theory teaching and experimental teaching.
