DAWNFILE is not visualizing the G4Torus with small pDphi. For example DAWNFILE is drawing only first torus with Dphi=7.5*deg for geometry that you may see below. The another visualizing driver (OIX, OGLIX) is displaying the both tori. ----------------------------------------------- Klens_fiber = new G4Torus("Fiber",0.*mm,50.*mm,500.*mm,0.*deg,7.5*deg); Klens_fiber_log = new G4LogicalVolume(Klens_fiber,LeadGlass,"Fiber_log", 0,0,0); Klens_fiber_phys = new G4PVPlacement(0,G4ThreeVector(0.0*mm,0.0*mm,500*mm), Klens_fiber_log,"Klens_fiber",World_log,false,1,false); Klens_fiber = new G4Torus("Fiber",0.*mm,50.*mm,500.*mm,0.*deg,7.0*deg); Klens_fiber_log = new G4LogicalVolume(Klens_fiber, LeadGlass, "Fiber_log",0,0,0); Klens_fiber_phys = new G4PVPlacement(0,G4ThreeVector(-200.0*mm,0.0*mm,600*mm), Klens_fiber_log,"Klens_fiber",World_log,false,2,false); ----------------------------------------------- I am currently using G4 v.8.0 on Debian platform with gcc 3.3.5 and DAWN 3.88a-GL.

In Geant4, the only viewer that is absolutely guaranteed to render all shapes correctly is the RayTracer. Other viewers may have some shapes that they do not know how to render. This is the case for DAWN. DAWN does not know how to render the Torus.
