These three views are calle

2、d the three views of the geometry,什么是三視圖,一個(gè)視圖只能反映物體的一個(gè)方位的形狀，不能完整反映物體的結(jié)構(gòu)形狀。三視圖是從三個(gè)不同方向?qū)ν粋€(gè)物體進(jìn)行投射的結(jié)果，另外還有如剖面圖、半剖面圖等做為輔助，基本能完整的表達(dá)物體的結(jié)構(gòu),如何看三視圖,機(jī)械制圖之三視圖基礎(chǔ)培訓(xùn),PART 02,The positive projections of a geometry at the rear, bottom, and right are called the main view, the top view, and the left view of the geome

3、try. These three views are called the three views of the geometry,由物體前邊向后做正投影得到的視圖,由物體上邊向下做正投影得到的視圖,由物體左邊向右做正投影得到的視圖,三視圖,主俯長(zhǎng)對(duì)正、主左高平齊、俯左寬相等 即: 主視圖和俯視圖的長(zhǎng)要相等 主視圖和左視圖的高要相等 左視圖和俯視圖的寬要相等,示例講解,機(jī)械制圖之三視圖基礎(chǔ)培訓(xùn),PART 03,The positive projections of a geometry at the rear, bottom, and right are called the main vie
