电力企业选购CAD系统原则的探讨

针对许多企业在CAD系统选购中存在片面的、错误的观念和做法,分析了导致CAN系统选购工作失败的原因,提出了“立足实用,兼顾先进,不盲目追求‘新、全’、高档次和高水平”的软、硬件购买原则,强调了软件选购要考虑软件公司和销售商的背景、软件的性能和功能及软件的易学易用等几个方面的问题．还详细论述了为什么要选国产名牌的微型机作为主机和要选主流的CPU芯片的问题．本文还就盗版软件的禁用和工程图纸扫描录入系统以及如何建立CAD网络系统提出了建议．

Principles of Purchasing CAD Systems for Electric Power Enterprises

Aimed at the existent one - sided and wrong ideas and action of many enterprises inpurchasing CAD systems, and based on the comprehensive analysis of large amount of materi-al, the author points out the causes which result in the failure in purchasing CAD systems.The principles of purchasing software and hardware are raised. That is basing on practicalityand advantage, not on pursuing "new and full", high - leve and high - grade blindly. Theauthor also puts forward emphatically the importance to consider the background of thesoftware corporations and suppliers, the capabilities and functions of software, and the abilityof being easily leamed and used. It is discussed in detail that why the national computers of fa-mous brand should be chosen as host computCrs and why the mainstream CPU should bechosen. In this paper the author also puts forward some original opinions about the embezz-led software and the system of scanning input for enginecring drawing. Valuable suggestionsare given to establish CAD network system.
