Computeraided design is usually associated with interactive puter graphics( known as a CAD system) . Computeraided design systems are powerful tools and are used in the mechanical design and geometric modeling of products and ponents. 計(jì)算機(jī)輔助設(shè)計(jì)( CAD) 是指用計(jì)算機(jī)來(lái)創(chuàng)造設(shè)計(jì)圖紙和產(chǎn)品模型。計(jì)算機(jī)輔助設(shè)計(jì)通常是與交互式計(jì)算機(jī)圖形學(xué)(稱(chēng)為 CAD 系統(tǒng))有關(guān)系的。 In CAD, the drawing board is replaced by electronic input and output devices. When using a CAD system, the des
