34 // G4CutTubs is a tube with possible cuts in +-Z.
35 // Implementation adapted from G4Tubs (subclass of G4Tubs) and
36 // from TGEo Ctube implementation (by A.Gheata, CERN)
37 //
38 // G4CutTubs(pName,pRMin,pRMax,pDZ,pSPhi,pEPhi,pLowNorm,pHighNorm)
39 // pName,pRMin,pRMax,pDZ,pSPhi,pEPhi are the same as for G4Tubs,
40 // pLowNorm=Outside Normal at -Z
41 // pHighNorm=Outsie Normal at +Z.
