A machine part is often drawn in the position it occupies in the assembly. However, in most cases this is not important. Dimensions are given in the form of linear distances, angles, or notes regardless of the dimensioning units being used. decimal fraction 小數(shù)fraction 分?jǐn)?shù)fractional inch 用分?jǐn)?shù)表示的英寸leave out 遺漏 刪去 省略 忽略omit 省去遺漏 leave out omit missThe beginner, however, should be cautious about leaving out hidden lines until experience shows when they can be safely omitted. drawing convention 繪圖慣例Chapter 6 Multiview projectioncylindrical surface 圓柱面element 素線deformity of cylinder space curve 空間曲線intersection 相交tangency 相切filletinterior corner 內(nèi)圓角roundexterior corner 外圓角runout 過渡圓角The side view of the railroad rail is quite blank. 鐵路導(dǎo)軌的旁視圖特別空。poor practice 蹩腳的實踐conventional edge (Page 151, ) 過渡邊透明的 transparent 不透明的 opaqueChapter 7 Sectional viewsDrafters use sectional views to improve the clarity of plex objects when the interior surfaces result in too many hidden lines.There are many types of sectional views, and a sectional view may replace one of the primary views. cutting plane 剖切平面full section 全剖In general, all visible edges and contours behind the cutting plane should be shown. Otherwise, a section will appear to be made up of disconnected and unrelated parts. A sectionlined area(畫剖面符號的區(qū)域) is always pletely bounded by a visible outline－never by a hidden line. Also, a visible line can never cut across a sectionlined area.section line 剖面線section lining 畫剖面符號sectionlining symbols 剖面符號title strip 標(biāo)題欄 title blockin the form of a note 以注釋的形式the correct method of drawing section lines is… 畫剖面線的正確方法是…..provided(倘若，以……為條件) that clarity is not sacrificed.Each section is pletely independent of the other and drawn as if the other were not present.take precedence (of) 優(yōu)先(于)semicylindrical surface 半圓柱面All cut surfaces here are part of the same object and the section lines must all run in the same direction as shown.half section 半剖視brokenout section 局部剖視revolved section 重合斷面removed section 移出斷面angular section 斜剖視offset section 階梯剖aligned section 旋轉(zhuǎn)剖inplete 不完整的pound section 復(fù)合剖視圖auxiliary section 輔助剖視圖T
