rightmost digit

Where taper and column pro-cuts,it usually utilizes characteristic of gather in side elevation to seek the cut line in the furthest right point,passing the top of taper to make cut line of gather circularity,finding out the cutting point in shadow of V side,which was thought that the point should be the furthest right.

利用计算机辅助设计给出了一种新的圆锥、圆柱正交相贯线最右点的求解方法。

It is able to provide a new method for the calculation of furthest right point of taper and column pro-cuts by CAD.

利用计算机辅助设计可给出一种新的圆锥、圆柱正交相贯线最右点的求解方法。

The conclude is that the drawing of ultraright-point of intersection curve of two cones with intersecting axes is gained.

运用解析几何理论证明轴线相交的两圆锥相贯线的平面投影是双曲线,证明了双曲线中心、双曲线渐近线、双曲线的共轭直径及双曲线相对于轴线的最右点都可以在画法几何中准确地通过作图方法得到,从而得出轴线相交的两圆锥相贯线最右点也可以通过作图方法得到的结论。
