本書為續(xù)丹主編的《工程圖學(xué)與實踐》的配套習題集，旨在配合教材幫助
學(xué)生通過必要的實踐環(huán)節(jié)，完成從基本形體構(gòu)成、零件設(shè)計與制造到裝配體設(shè)
計與制造的表達訓(xùn)練，并通過后一章完成綜合實踐環(huán)節(jié)的綜合表達能力訓(xùn)練。
本書習題編排順序與配套教材完全一致，共分四篇，即產(chǎn)品加工制造認識篇、
形體表達基礎(chǔ)理論篇、機械產(chǎn)品表達篇、實踐應(yīng)用篇，具體內(nèi)容包括機械加工
制造技術(shù)、基本幾何體的表示方法、組合體的表示方法、機件的圖樣表示方法、
零件的表示方法、裝配體的表示方法、圖樣表達綜合實踐，各章均設(shè)置了適當
數(shù)量、不同難度的習題。
本書可作為高等院校機類、電類各專業(yè)制圖課程的配套習題集，也可作為高職高專等其他各類院校相關(guān)專業(yè)的制圖課程配套習題集。與本習題集配套的《工程圖學(xué)與實踐》已由機械工業(yè)出版社同步出版，供讀者選用。

本書主要根據(jù)《工程圖學(xué)與實踐》教材的特點，結(jié)合高等學(xué)校工程圖學(xué)課程教學(xué)指導(dǎo)分委員會 2019年修訂的《高等學(xué)校工程圖學(xué)課程教學(xué)基本要求》及近年來發(fā)布的《技術(shù)制圖》和《機械制圖》有關(guān)國家標準，在普通高等教育“十一五”規(guī)劃教材《 3D機械制圖習題集》的基礎(chǔ)上，結(jié)合編者團隊 19年的教學(xué)實踐總結(jié)論證，基于西安交通大學(xué)本科教改項目規(guī)劃重新編寫完成。
本書由淺入深、循序漸進設(shè)置題目，旨在讓學(xué)生在練習中完成將工程圖學(xué)的理論知識應(yīng)用于機械產(chǎn)品從基本形體構(gòu)成、零件設(shè)計與制造，到裝配體設(shè)計與制造的表達訓(xùn)練，并通過后一章的綜合實踐環(huán)節(jié)完成一次綜合表達訓(xùn)練。為配合配套教材所遵循的“實踐→認識→再實踐→再認識”的認知規(guī)律，本書重在實踐，訓(xùn)練學(xué)生三維設(shè)計表達與二維工程圖表達相互融合和交互式推進的、三維實體設(shè)計表達方法與二維工程圖表達方法并重的工程圖表達能力。
具體而言，本書具有以下特色：
1
）本書力求讓學(xué)生在練習中體會并構(gòu)建三維實體結(jié)構(gòu)表達和二維投影表達相融合的知識體系，訓(xùn)練將傳統(tǒng)的工程制圖與現(xiàn)代的建模表達方法融為一體的設(shè)計思維。

2
）綜合培養(yǎng)三維建模和二維圖樣表達能力。習題選擇與編排由淺入深，循序漸進，通過題目的練習，學(xué)生能夠獲得應(yīng)用三維設(shè)計軟件進行實體建模的思路和方法，掌握生成、識讀和完善二維工程圖樣的技能，并能獲得利用儀器或徒手進行繪圖的能力。

言
3
）緊扣《工程圖學(xué)與實踐》教材，滿足教學(xué)實踐環(huán)節(jié)的需要，在教材內(nèi)容學(xué)習的基礎(chǔ)上，讓學(xué)生通過實踐加深認知。

4）選題新穎，題目數(shù)量和難度適當，能夠保證學(xué)生進行足夠的訓(xùn)練。

5
）全書相關(guān)內(nèi)容均按照《技術(shù)制圖》和《機械制圖》現(xiàn)行國家標準進行了更新。

參與本書編寫的人員及分工為：張興武編寫章，續(xù)丹編寫第二章節(jié)～第三節(jié)、第三章節(jié)、第七章部分題目，王小章編寫第二章第四節(jié)、第三章第五節(jié)、第四章第六節(jié)，張群明編寫第三章第二節(jié)～第四節(jié)，梁慶宣編寫第四章節(jié)～第五節(jié)，史曉軍編寫第五章、第六章題目中的技術(shù)要求內(nèi)容，許睦旬編寫第六章主體內(nèi)容、第七章部分題目。本書由續(xù)丹任主編并完成全書統(tǒng)稿。內(nèi)封參編署名順序與所負責編寫章節(jié)順序一致，重要程度不分先后。
