【正文】 he designer can then subject the design to a variety of engineering analyses and can identify potential problems （ such as an excessive load or deflection） .The speed and accuracy of such analyses far surpass what is available from traditional methods. 在 CAD（計算機輔助設計）中，傳統(tǒng)的畫圖板被電子輸入和輸出設備所替換。當使用 CAD 系統(tǒng)時，設計者可以使對象概念化以便更容易在圖形屏幕上設計，并且可以考慮替代設計或快速地修改一個特定的設計來達 到必要的設計要求或變化。 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 characteristics， such as movable or stationary ， can be assigned different colors on the display. CAD 使二維圖紙多重視圖變?yōu)榭赡?，并且圖形可以在大小不同的圖層里重生。計算機輔助設計和計算機輔助制造常常是和 CAD / CAM系統(tǒng)相結合的。 The emergence of CAD/CAM has had a major impact on manufacturing， by standardizing product development and by reducing design effort， tryout， and prototype work； it has made possible significantly reduced costs and improved productivity. The twoengine Boeing 777 passenger airplane， for example, was designed pleted by puter（ paperless design ） .The plane is constructed dire
