The Designing And Implementing Of The CAD System Of Glass Curtain

Nowadays glass curtain engineering develops rapidly, while CAD software engaged for glass curtain design is relatively rare. Glass curtain has a variety of normative forms, this makes it easy to design glass curtain by developing and using professional software. This paper discusses problems of the structural analysis, calculation and plotting the shop drawings of glass curtain and concludes the general arithmetic for the tasks just mentioned. The paper puts forward a set of schemes which deals with glass curtain engineering via a piece of computer software, and implements the computer software-glass curtain CAD system.The system uses Windows 2000 as the developing platform and VC++6.0 as the developing tool and AutoCAD as the graphics-supporting environment. The system also employs the C/C++ programming technique under the Windows operating system, the MFC foundation class library, AutoCAD developing tool-ObjectARX and other techniques. The system is established using the Object-oriented programming method, it has relatively high stability and efficiency.The system has two modules, they are design&calculation module and plotting module. The design&calculation module mainly performs the pre-process tasks such as collecting data using Windows standard controls, checking the validity of the data via functions and finally performing comprehensive analysis and calculation with the data. The plotting module is responsible for the post-process tasks which cover outputting the result of the calculation in a text file so that the user can check the calculation and plotting the shop drawings in the AutoCAD environment based on the data exported from the design&calculation module.
