Application of cad
Advantages of cad for large as well as small merchant manufacturing firms include:
Use and easy modification of previous design permitting easy changes to be processed more quickly;
Design improvements created by features allowing designers to try out a dozen or a hundred different variations where previously they might have been limited to building perhaps three or four prototype models;
Faster construction of drawings :design time with cad ranges from 5 go 100 times as fast as manual systems ,with 2 to 6 times as fast being typical;
Cad buys time.It permits users to try more designs ,more options ,and more approaches to the optimum product .where before it took tha bending of metal to see if a concept was viable ,now the computer can test concepts in an iterative manner so that the metal-bending now is done only for the best approaches.Since the operations are now simulated the time needed to evaluate many designs is even less than the time to prepare just one engineering model for evaluation.Mistakes are made on the computer display screen where they cost little,instead of in the hardware which,besides being expensive,takes time to create and evaluate.It is not in conceivable that ten to twenty years of product innovation cold have been done in cad facilities in months,with the products of today falling out as the best approaches,given the materials and factories known to exist for these products.The time compression and the subsequent savings,when considered over time,are really astounding.

应用计算机辅助设计
对大型和小型商业企业计算机辅助设计制造的优势包括：
使用与以前的设计很容易修改,允许很容易改变,更迅速地处理;
通过允许设计人员尝试了几十个或那些之前可能被限制在100个不同版本的功能建设创造设计改进或许三,四原型模式;
施工速度快,图纸：设计与CAD时间范围从5到100倍的速度为手动系统,2至6倍,是典型的快;
民航处购买的时间.它允许用户在尝试更多的设计,更多选择,更多的办法,以最佳的产品.在收到了塔金属弯曲,看看一个概念是可行的,现在的电脑可以测试在一个迭代的方式,使金属弯曲现在是做了最好的办法只有概念.由于业务需要现模拟评估许多设计的时间,比时间准备评估只是一个工程模型少.误区,是基于电脑显示屏幕,他们的小,而不是在硬体,除了是昂贵的,需要时间去创建和评估费用.这不是在想像,10至20冷年的产品创新已经在CAD设施做个月,下降为最佳办法今日的产品,由于材料和工厂已知存在的这些产品.压缩的时间和随后的储蓄,认为随着时间的推移,实在令人惊叹.
