GC_MakeConicalSurface (const gp_Ax2 &A2, const Standard_Real Ang, const Standard_Real Radius)  
A2 defines the local coordinate system of the conical surface. Ang is the conical surface semiangle ]0, PI/2[. Radius is the radius of the circle Viso in the placement plane of the conical surface defined with "XAxis" and "YAxis". The "ZDirection" of A2 defines the direction of the surface's axis of symmetry. If the location point of A2 is the apex of the surface Radius = 0 . At the creation the parametrization of the surface is defined such that the normal Vector (N = D1U ^ D1V) is oriented towards the "outside region" of the surface. Status is "NegativeRadius" if Radius < 0.0 or "BadAngle" if Ang < Resolution from gp or Ang >= PI/  Resolution. More...

This class implements the following algorithms used to create a ConicalSurface from Geom.
The "ZAxis" is the symmetry axis of the ConicalSurface, it gives the direction of increasing parametric value V. The apex of the surface is on the negative side of this axis.
The parametrization range is : U [0, 2*PI], V ]infinite, + infinite[
The "XAxis" and the "YAxis" define the placement plane of the surface (Z = 0, and parametric value V = 0) perpendicular to the symmetry axis. The "XAxis" defines the origin of the parameter U = 0. The trigonometric sense gives the positive orientation for the parameter U.
When you create a ConicalSurface the U and V directions of parametrization are such that at each point of the surface the normal is oriented towards the "outside region".

A2 defines the local coordinate system of the conical surface. Ang is the conical surface semiangle ]0, PI/2[. Radius is the radius of the circle Viso in the placement plane of the conical surface defined with "XAxis" and "YAxis". The "ZDirection" of A2 defines the direction of the surface's axis of symmetry. If the location point of A2 is the apex of the surface Radius = 0 . At the creation the parametrization of the surface is defined such that the normal Vector (N = D1U ^ D1V) is oriented towards the "outside region" of the surface. Status is "NegativeRadius" if Radius < 0.0 or "BadAngle" if Ang < Resolution from gp or Ang >= PI/  Resolution.
