立体轴测图的解析画法

Making Pictorial Drawing of Solid by Analysis

利用解析法建立立体上各点的空间坐标、轴测图坐标与X Y平面坐标之间关系式,把各点的空间坐标通过轴测坐标转换成X Y平面坐标,进而画出立体的轴测图.用解析画法可以做到准确作图,并为计算机编程绘图提供基本方法.

The author introduced a method that established the coordinates of key points on the solid by analysis. Moreover, it constructed the equations between the coordinates of the pictorial axes and the coordinates on the X-Y plane. Finally, we could change the coordinates of key points on the solid into the coordinates on the X-Y plane through the equations. Using the method the pictorial drawing of the solid could be made more exactly.
