Question Special cylindrical sector 

Forum: Geometry
Date: 17 Feb, 2006
From: Emanuele Leonardi <Emanuele Leonardi>

To create a cylindrical sector I can use G4Tubs and set the following
parameters:

- internal radius
- external radius
- starting phi
- dphi (angular span of the sector)

I now want to create a solid which is still a sector of a cylinder but
where the starting phi at the internal radius is different from the
starting phi at the external radius. To help visualizing this, you may
think of an iris diaphragm used in photographic cameras: the solid I have
in mind is one sector of this diaphragm.

This looks like an extension of the G4Tubs class but I could not figure
out how to create it with any of the exisiting geometrical classes.

Can anybody help me?

Thanks

             Emanuele Leonardi
