Standard_Real  Radius () const 
 Returns the radius of this circle. More...


gp_Ax1  XAxis () const 
 Returns the "XAxis" of the circle. This axis is perpendicular to the axis of the conic. This axis and the "Yaxis" define the plane of the conic. More...


gp_Ax1  YAxis () const 
 Returns the "YAxis" of the circle. This axis and the "Xaxis" define the plane of the conic. The "YAxis" is perpendicular to the "Xaxis". More...
