Coordinates for the center: J=Y1+AuxPoint[1]，K=Z1+AuxPoint[2]。
Coordinates for the end point:
X=X1+EndPoint[1]，Y=Y1+EndPoint[2]，Z=Z1+EndPoint[3]。

Draw an arc via the radius on XY plane. The value of AuxPoint[1] is the radius of
the circle on XY plane and here the value of AuxPoint[2] is meaningless.
If the value of AuxPoint[1] is greater than 0, it is a minor arc.
If the value of AuxPoint[1] is less than 0, it is a major arc.

Draw an arc via the radius on ZX plane. The value of AuxPoint[1] is the radius of
the circle on ZX plane and here the value of AuxPoint[2] is meaningless.
