In the mechanical industry,AutoCAD is the most popular software and has a characteristic of open.In order to improve design quality and efficiency,currently more common practice is to conduct secondary development of AutoCAD software. This graduation design takes the parametric drawing of magnetic separator parts as the example.Then,the realizing process of redevelopments in AutoCAD is presented in detail ,through analyzing and studying the secondary development of AutoCAD based on magnetic separator.We use the Visual LISP as a platform,then apply LISP language compile parametric drawing programs,and DCL language create a man-machine exchange dialogue frame.We also learn the load on the menu of CAD.At last,when we finish the secondary development of AutoCAD based on magnetic separator,we can get magnetic separator parts diagram automatically by clicking on the new menu of CAD and inputing data into the dialog box. The practice indicates the secondary development of AutoCAD is powerful and plays a very important role in the design of the magnetic separator.so,it is a very significant subject.
