摘要
本文介绍了坐标面的垂直面上圆的轴测投影的一种比较简便的画法。一般平面上圆的轴测投影是椭圆,本文通过理论推导计算作出了一种表格,只要知道平面对坐标面的倾角通过查表立即可得到椭圆的长轴短轴的长度及方向角,从而可较方便地画出椭圆。此表格还可以指导轴测图种类的选用及轴测方向合理地设置。
A simple table for drawing axnometric projection of a circle is mainly intorduced in this paper. According to the table lengths of major and minor axes and direction angle of an ellipes is soon found, if the slope angle between a plane and coodinate planes is known, so as to draw the ellipse easily. This table can be also used to select axnometric projection drawing kinds and arrange the axnometric axes directions reasonably.
