【正文】 analyses far surpass what is available from traditional methods. 在 CAD(計(jì)算機(jī)輔助設(shè)計(jì))中,傳統(tǒng)的畫圖板被電子輸入和輸出設(shè)備所替換。當(dāng)使用 CAD 系統(tǒng)時(shí),設(shè)計(jì)者可以使對象概念化以便更容易在圖形屏幕上設(shè)計(jì),并且可以考慮替代設(shè)計(jì)或快速地修改一個(gè)特定的設(shè)計(jì)來達(dá) 到必要的設(shè)計(jì)要求或變化。因而設(shè)計(jì)者可以提供多種工程分析并且可以識別潛在的問題(如過負(fù)荷或變形)。這些分析的速度和準(zhǔn)確性都遠(yuǎn)遠(yuǎn)超過了傳統(tǒng)的方法。 Draft productivity rises dramatically. When something is drawn once, it never has to be drawn again. it can be retrieved from a library ,and can be duplicated, stretched, sized, and changed in many ways without having to be redrawn。 Cut and paste techniques are used as laborsaving aids. 設(shè)計(jì)生產(chǎn)率的提高是顯著的。當(dāng)某些圖形被繪制一次后,就沒必要再畫第二次。它可以從圖形庫中恢復(fù),可以被復(fù)制,拉伸,改變大小,和其他許多方面的改變而無需重新繪制。剪切和粘貼技巧作為節(jié)省勞力的助手被使用。 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)榭赡埽⑶覉D形可以在大小不同的圖層里重生。它使機(jī)械工程師有能力放大甚至最小的部件來確定構(gòu)件是否裝配合適。對于具有不同特性的零部件,如移動(dòng)或靜止,可以指定不同的顏色在顯示屏上標(biāo)示。 Designers have even more freedom with the advent of 3D parts and manipulat
