关于确立CAD软件绘制标准化工程图地位的探讨

Discussion on Establishing Position of Drawing the Standard Engineering Design in CAD Softwares

工程图样作为工程技术信息交流的必要手段，在工程设计与创造中起到举足轻重的作用，而繁琐的手工绘图又一直困扰着工程技术人员，计算机物辅助绘图为解决这一问题提供了有利手段，但是工程图样既然作为交流文件，它的图形、标记以及表达形式都要严格执行《机械制图国家标准》．而目前CAD绘图软件中普遍缺少处理机械图样标准化功能的现象，必然要直接影响绘制工程图的质量和速度．本文的目的在于研究CAD软件的绘图功能与我国工程图标准化技术的联系，以求在典型软件中开发出明确贯彻标准化工程图样的相应功能．

Engineering designs work as necessary means of information exchange in engineeingtechnology and play on important part in engineering designing and making. Orerlaboratemannal drawing has always perplosed engineering technician and nowadays, CAD has pro-vided a Powerful method in solving this problem. As engineering drawing works as a sort ofexchange document, its pattern, mark and its expression from must perform strict1y the 'Na-tional Standard of Mechanical Drawing'. Now there is lack of sandardized function of me-chanical drawing in CAD softwares, which directly affects the quality and sped of drawingengineering designs- This paper is to research on the connection between CAD softwaredrawing function and standardized technique softwares, developing corresponding function incarrying out standardized engineering designs,
