摘　　要：通过对正等轴测图中平行于坐标面圆的四心法作图进行分析,提出了一种简便易行的椭圆简化画法,该方法不仅只适用于正等轴测图,而且适用于任何等轴测的情况.用此种方法可解决以往需要用多种绘图方法才能解决的问题.This four-center method of circular isometric project paralleled coordinate plane are analysised, and deuces a simple predigestion method to make drawing wide of isometric project ellipse. This method not only applies to wide of isometric projection, but also applies to any rectangular axonometric projection. This method can solve many different questions which need solved in many different ways before.
