//
// class for Geant-shape TRD1
// derived from baseclass HGeoBasicShapes
//
// To read the 8 xyz-points from database or file the function readPoints(...)
// in the baseclass is used.
//
// The technical coordinate system of a TRD1, which sits in CAVE and is not
// rotated, is the laboratory system. The y-axis points from the smaller side to
// the larger one. That's the same definitition as for a TRAP and different from
// the Geant-definition for a TRD1.
// Therefore a transformation is needed:
//              x-technical = - (x-Geant)
//              y-technical = z-Geant
//              z-technical = y-Geant
// This is described by cgRot.
//
