摘　　要：在研究传统菱形法绘制正等测椭圆的基础上 ,运用逻辑分析和几何分析的方法 ,提出了一种六点共圆、三线共点的椭圆简捷画法 ,作图简便、快捷 。Based on the traditional rhombus method to drawing the isometric ellipse, this paper uses the method of logic analysis and geometric analysis, puts forward a kind of method of drawing the isometric ellipse in which six points are on the circle and three lines intersects at one point. Such method is simple and quick in drawing and high in efficiency.
