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)



图1



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;
