利用ObjectARX开发工程图系统

he methods of transforming 3D solid modal to 2D drawing in AutoCAD and the steps of creating the three-view drawing of the solid modal with the command of MView are introduced. In order to making up for the defects of these methods, the engineering drawing system is developed based on these methods with the secondary development tool of ObjcetARX. The system has friendly user interface, it can be operated easily and conveniently, and it can reduce many repeated operations, improve the design efficiency. Furthermore, the drawing is created in the model space, which makes the user’s operation more convenient. The realization of the engineering drawing system improves that developing the application program with ObjcetARX is a effective method of strengthening the function of AutoCAD, enhancing the design efficiency and lowering labor intensity of user.
