The twoengine Boeing 777 passenger airplane， for example, was designed pleted by puter（ paperless design ） .The plane is constructed directly from the CAD/CAM software developed（ an enhanced CATIA system） and no prototypes or mockups were built ， such as were required for previous models. CAD/CAM 的出現(xiàn)對(duì)制造業(yè)產(chǎn)生了重大影響，通過產(chǎn)品開發(fā)的標(biāo)準(zhǔn)化和減少設(shè)計(jì)工作量，試用，和原型的工作；它有可能大大降低成本和提高生產(chǎn)力。指令（程序）是計(jì)算機(jī)生成的，它們可以由程序員修改優(yōu)化刀具路徑。計(jì)算機(jī)輔助設(shè)計(jì)和計(jì)算機(jī)輔助制造常常是和 CAD / CAM系統(tǒng)相結(jié)合的。通過有限元分析，應(yīng)力加到計(jì)算機(jī)模型上并且以圖形化的方式顯示其結(jié)果，在產(chǎn)品物理原型生產(chǎn)之前，對(duì)設(shè)計(jì)中的任何內(nèi)在問題給設(shè)計(jì)者一個(gè)快速的反饋。 CAD makes possible multiview 2D drawings ， and the drawings can be reproduced in different levels of reduction and enlargement. It gives the mechanical engineer the ability to magnify even the smallest of ponents to ascertain if assembled ponents fit properly. Parts with different ch
