补充资料：在AutoCAD中偏心圆锥与偏心圆台实体的画法
现在要画一个偏心圆锥,底面在WCS的XY平面上,圆心(0,0,0),半径100,顶点(300,0,400)在ZX平面上.
1)连接PA,PB. A(-100,0,0) B(100,0,0)

在当前坐标下:
2)延长PA到C,使PA=CA;延长PB到D,使PB=DB;
3)连接CD;
4)以CD为直径画圆;
5)用XLINE命令中的二等分选项作角CPD的角平分线PO,交CD于O;
6)过O作CD的垂线,交圆于E,F;
图2
7)用三点UCS命令,取三点为:O,P,C;
8)过点O作PO的垂线GO,交PC于G;
图3
9)再次用三点UCS命令,取三点为O,F,G;
10)现在就可以画椭圆锥了!
cone-e-c-捕捉O点-捕捉F点-捕捉G点-a-捕捉P点;
