可视化机械设计软件开发技术的研究

利用Visual Basic 6．0和Visual FoxPro 6．0语言对应用程序的调用功能、VisualBasic 6．0、VisualFoxPro 6．0和Visual LISP语言对纯文本文件的读写功能及Windows32 Application Programming Interface函数，实现应用程序之间的相互调用和数据传输；利用AUTOCAD2000系统的对Visual LISP应用程序的自动加载功能，实现机械工程图的自动化绘制，可开发出集机械设计计算、机械工程数据库管理及机械工程图自动绘制等多项功能于一体的可视化机械设计软件。这种开发技术既简单又实用，能够充分发挥多种可视化语言的特长，提高应用软件的开发效率，降低应用软件的开发成本。

Research on Development of Visual Mechanical Design Software

To make use of calling functions with which Visual Basic 6. 0 and Visual FoxPro 6. 0 executes application programs, reading-writing functions with which Visual Basic 6.0 ,Visual FoxPro 6.0 and Visual LISP read and write text files and windows32 Application Programming Interface fuctions, one can realize the calling and data transmissions between application programs. To make use of autoexec function with which AutoCAD2000 system executes Visual LISP application programs, one can make the computer automatically draw mechanical engineering drawings. Therefore visual mechanical design sotfware can have been developed, which can do mechanical design computing, manage mechanical engineering databases and automatically draw mechanical engineering drawings. This technic is simple and practical. It can make full use of the specialities of many visual languages, improve developing efficiencies of application software and reduce developing cost of application software.
