随着CAD技术应用水平的提高,越来越多的电子文件产生。如何保存并再利用这些文件,从目前来看光盘存储技术是最有效的手段之一。上海机电设计院作为工程设计单位,CAD出图率已高达95%以上,其设计文件由原来的以纸介质为主转为纸介质与电子介质并存。电子设计文件在存储、输出、处理等方面具有纸质设计文件不可比拟的优越性。而纸质设计文件也有其存在的价值,因为其耐用性和安全性都是值得信任的。这两类需要归档的文件有着各自的特点和存储方
With the improvement of the application of CAD technology, more and more electronic files are produced. How to save and reuse these files, from the point of view CD-ROM storage technology is one of the most effective. Shanghai Mechanical and Electrical Design Institute as an engineering design unit, CAD drawing rate has been as high as 95% of the design documents from the original paper-based media into paper and electronic media co-exist. Electronic design documents in the storage, output, processing and other paper design documents incomparable superiority. Paper design documents also have their value because they are trustworthy for their durability and safety. The two types of documents that need to be archived have their own characteristics and storage
