You are right. With your parameters (copied from your earlier posting, reproduced below), the G4BREPSolidCylinder is invisible to RayTracer. It looks like a geometry problem. Gabriele?

  G4Point3D o (0,0,0);
  G4Point3D a (0,0,1);
  G4Point3D d (1,0,0);
  G4double r = 1;
  G4double l = 1;
  G4BREPSolidCylinder* brep = new G4BREPSolidCylinder("name",o,a,d,r,l);
