Reaseach on secondary development and operation mechanism based on ObjectARX and it's application

This paper analyses the features and function of ObjectARX for the secoudary development of AutoCAD,and illustrates the process and method ObjectARX.Through the AutoCAD graphics database structure,composition and ObjectARX a variety of function and such as categories,operational mechanisms of ObjectARX based on secondary development is studied.The structure of ObjectARX application is also introduced.Performing the structural analysis software before and after the treatment process,as an example,the secondary development of a mechanism in accordance with the ObjectARX,given the creation of entities,physical function interface applications.The significance of learning and mastering ObjectARX is proved.
