Question G4EllipticalCone understanding problem 

Forum: Geometry
Date: 18 Nov, 2011
From: Matthew Szydagis <Matthew Szydagis>

I am having trouble figuring out what the parameters mean for G4EllipticalCone, and my attempts to understand from G4EllipticalCone.cc/hh and the Geant4 documentation at http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/ch04.html

have failed.

Documentation appears inconsistent, with the semi-axes being defined as dimensionless it seems, but in examples I found around this forum, it appears to have dimensions. In short, I am quite lost.

Could someone please help me understand the arguments in  G4EllipticalCone(const G4String& pName,              
                          G4double  pxSemiAxis,
                          G4double  pySemiAxis,
                          G4double  zMax,
                          G4double  pzTopCut)

And please can you tell me concretely, how do I create a cone with one radius of 3.1877 cm (both semi-axes equal -- circular cone), and at the upper cut radius of 2.54 cm, both semi-axes equal again.

(I know I can make a cone with G4Cons that is circular, but I want to do it with G4EllipticalCone instead because I want to start with a circular cone and perturb it elliptically.)
