52、程中的流暢性。 在三維設(shè)計(jì)軟件的廣泛使用，可以分為高端和中端cad系統(tǒng)，高端的三維cad軟件主要的i - deas軟件，地下，pro / engineer的，catia的，中檔三維cad系統(tǒng)主要solidworks中，solidedges，聯(lián)合化療，發(fā)明等。一般制造業(yè)企業(yè)，對(duì)solidworks的強(qiáng)大功能來(lái)完成一般的設(shè)計(jì)任務(wù)，這是它的易用性和效率也引起了越來(lái)越多用戶的關(guān)注。 三維設(shè)計(jì)，從簡(jiǎn)單的幾何模型生成工具軟件的經(jīng)驗(yàn)，技術(shù)，產(chǎn)品的模型變量控制，最終形成一個(gè)完整的企業(yè)數(shù)字化進(jìn)程。三維設(shè)計(jì)軟件的應(yīng)用大大提高了產(chǎn)品設(shè)計(jì)和開(kāi)發(fā)效率。 相比二維設(shè)計(jì)（cad）的三維設(shè)計(jì)功能最大的特點(diǎn)是造型技術(shù)的使用，整

53、個(gè)設(shè)計(jì)過(guò)程的相關(guān)技術(shù)。三維設(shè)計(jì)軟件不僅是一個(gè)強(qiáng)大的建模功能，而且還提供了廣泛的技術(shù)支持。包括對(duì)設(shè)計(jì)意圖，設(shè)計(jì)和系列化設(shè)計(jì)重用，例如，描述。 成三維零件設(shè)計(jì)，裝配設(shè)計(jì)和工程圖紙?jiān)O(shè)計(jì)產(chǎn)生的三個(gè)階段。關(guān)系到整個(gè)設(shè)計(jì)過(guò)程，使修改后的設(shè)計(jì)會(huì)影響到設(shè)計(jì)階段的其他結(jié)果的任何階段，從而保持了在設(shè)計(jì)環(huán)境中的各種模型的一致性，從而提高設(shè)計(jì)效率。 1.1.1零件設(shè)計(jì) 零件的設(shè)計(jì)是三維設(shè)計(jì)的基礎(chǔ)。零部件一般都在三維實(shí)體的形式，如圖1.1所示裝載在“桶”型車(chē)輛的零配件。從建模，參數(shù)化特征造型和三維實(shí)體零件設(shè)計(jì)的角度來(lái)看，已成為一種主流技術(shù)。在作為對(duì)一個(gè)三維實(shí)體模型部件的形態(tài)特征的不同組合的特征稱(chēng)為處理實(shí)體的不同部分。不
