// Class description:
33
//
34
// The polyconical solid G4BREPSolidPCone is a shape defined by a set of
35
// inner and outer conical or cylindrical surface sections and two planes
36
// perpendicular to the Z axis. Each conical surface is defined by its
37
// radius at two different planes perpendicular to the Z-axis. Inner and
38
// outer conical surfaces are defined using common Z planes:

// G4double start_angle,
