The Second Development System Of Generator Support With Ring Type Beam In Hydroelectric Power Station

In this paper, at first analyses the background and the development of AutoCAD technology. And then introduces and contrasts several methods of AutoCAD's second development, and points out the feasibility and inevitability of using ObjectARX in developing the generator support with ring type beam. And then expounding the character ^ function and the class library of ObjectARX2002. The design theory of the generator support with ring type beam is analysed in this paper. And brings forward the basic idea of using ObjectARX2002 in the AutoCAD's second development, points out the research contents> the implement project and several important modules of this system, and the resolvent of some important problems are introduced. At last, the paper offers the help of installing and using, and the work of this paper is summarized, the direction of the research is pointed out.This paper adapts the VC++6.0 developing interface with ObjectARX2002 to program the generator support with ring type beam CAD system which has window style user interface by selecting the shared dynamic linked MFC library. The system achieves the visual and automation by interaction between the MFC dialog and AutoCAD graphic system. It makes full using of the Object-oriented developing function provided by the ObjectARX2000. The user can interact with the system in higher level by using Object-oriented data encapsulation mechanism to implement the data abstraction and information reservation.
