Representing fastening pieces and solid pieces緊固件及實(shí)心件畫法緊固件及實(shí)心件畫法The contact surface or fitting surface of two parts is represented as a line, while the noncontact surface or nonfitting surface is represented as two lines even small clearance. 兩個(gè)零件的接觸面或配合表面只畫一條線，而非接觸面或配合表面兩個(gè)零件的接觸面或配合表面只畫一條線，而非接觸面或配合表面之間有間隙處應(yīng)畫成兩條線。之間有間隙處應(yīng)畫成兩條線。請(qǐng)點(diǎn)擊鼠標(biāo)左鍵顯示后面內(nèi)容請(qǐng)點(diǎn)擊鼠標(biāo)左鍵顯示后面內(nèi)容 If the structure of a certain part is not clearly represented and will thus affect the understanding of its fitting relationship and function, the part must be drawn separately and marked with “xx direction” near the corresponding view indicating with arrows and capital letters the projection direction. 當(dāng)某個(gè)零件的結(jié)構(gòu)未表達(dá)清楚，且對(duì)理解配置關(guān)系或部當(dāng)某個(gè)零件的結(jié)構(gòu)未表達(dá)清楚，且對(duì)理解配置關(guān)系或部件功能有影響時(shí)件功能有影響時(shí) , 應(yīng)單獨(dú)畫出該零件應(yīng)單獨(dú)畫出該零件 , 并在其上方注明并在其上方注明 “零件零件”, 在相應(yīng)視圖附近用箭頭指明投射方向在相應(yīng)視圖附近用箭頭指明投射方向 , 并注明相應(yīng)的大并注明相應(yīng)的大寫字母。寫字母。 To represent the internal details of a machine or assembly, we can represent some parts as a cutaway drawing along the fitting surface. In this representation, the section lines of the fitting surface are not needed, but the section lines
