The Development And Research Of The Parametric Design And Drawing System For Highway Culvert

At present, the certain research results on the development and applying of the highway culver CAD software have been obtained in our country, the domestic culvert CAD software has been more mature, and has been applied widely. At the same time, the software shows various degrees of shortcomings in practice. According to the standardize of the culvert design, the theory of parametric design and drawing was studied in the article, based on which the cu1vert CAD system was developed by means of using ObjectARX combined with VC++.In the article, the author firstly analyzed the organization structure of culvert data and the method by which the length of culvert was calculated. At the same time, the author discussed the methods of parametric design and drawing. Then an Object-Oriented method was applied to develop the AutoCAD for two times. The software system of the cu1vert for highway was developed based on the above methods. Depending on the system, to a large extent, we can improve the efficiency of the tube design for highway. Meanwhile, depending on the deriving and inheriting techniques of the C++, the interfaces for the other modules of cu1vert CAD were reserved.In conclusion, using the techniques of MFC and ObjectARX, the author completed the development of culvert design system. The culvert design system combines with the standard drawing closely, and since the development of culvert design system has applied the Object-Oriented methods, the culvert design system can easily be comprehended and maintained.
