任意位置回转体正面斜轴测图的简易画法

根据正面斜轴测图中物体的正面次投影与其正面正投影完全相同的特点，可简化一般位置圆的正面斜轴测图的画法；画一般位置回转体的关键是画其两端的圆，依共轭直径周八段圆弧画近似椭圆，可简单画任意回转体正面斜轴测图的方法。结合一零件正面同测圆的绘制，具体介绍这种简易的画任意位置回转体正面斜轴测图的方法。

Simple and Easy Drawing Method of Elevational and Synclinal Axonometry Drawing of Wanton Revolving Object

According to the feature that frontal subprojection and frontal right projection of the object are entirely the same in the front elevational oblique axis measuring drawing. The drawing method of front elevational oblique hos measuring drawing can be simplified.The key of drawing general position revolving object is drawing circles on the both sides.On the basis of conjuqate diameter draw approximate ellipse with eightstage circle arc,may simplify the method with which draw wanton revolving Object front elevational oblique axis measuring drawing.Combining with drawing a frontal elevational oblique axis measuring drawing a frontal elevational oblique hos measuring drawing of spare partS,a method is specificly introduce With which draw wanton position revolving object front oblique axis measuring drawing.
