农业机械工程图纸管理系统的研究和开发

在Ｗｉｎｄｏｗｓ９５操作平台上，用ＯｂｊｅｃｔＡＲＸ开发了一套内嵌ｕｔｏＣＡＤ ｒ１４的农机图纸系统。该系统应用面向对象理论和ＯＤＢＣ（Ｏｐｅｎ Ｄａｔａｂａｓｅ Ｃｏｎｎｅｃｔｉｏｎ）技术，实现了ＡｕｔｏＣＡＤ Ｒ１４内部的多文档－视（ＭＤＩ）结构。该系统在已有工程图像管理系统的基础上，针对农机企业的特点，有所创新和完善。同时使用了ＭＦＣ（Ｍｉｃｒｏｓｏｆｔ Ｆｏｕｎｄａｔｉｏｎ Ｃｌａｓｓｅｓ）技术，使得该系统的功能更强大，界面更友好，可视化程度更高。

Study on Engineering Drawings Management of Agricultural Machinery

Engineering drawings are fundamental to CAD and CAM. Management of engineering drawings in an agricultural machinery factory was disscussed in this paper. An engineering drawing management software (JDMS 1.0) using ObjectARX and Win95 platform was developed, which was embeded in AutoCAD R14 software and can realize multi document view (MDI). The developed system enhances the functions such as inserting drawing and drawing preview compared with the existing drawing management systems. The interfaces of this software become more friendly, the functions more powerful and the visualization better as a consequence of adopting the technology of Microsoft Foundation Classes (MFC).
