Hi all, Dr. Vladimir GRICHINE kindly suggested me to replace the following constants used in my code to construct solids const G4double TwoPI = 3.1415926 * 2.; const G4double ROOT2 = 1.4142136; to more accurate ones twopi std::sqrt(2.) because geometry constructers are very sensitive to accuracy of the constants. After replacing these constants, warnings issued by G4Navigator::ComputeStep() completely disappeared both for G4Polycone and G4Tubs (although with G4Polycone a warning of overlapping volume is still displayed. As indicated in my post in geometry/542 it should be spurious). Lesson learned: to construct solids (especially with axial symmetry) we have to use accurate constants such as twopi and std::sqrt(2.). Thanks Vladimir. Yours, Kazuyoshi
