Hi, I am a bit confused about the the dump of an simple polyhedra. Why are the tangent distances to the surfaces and the R values of the corners the same? I expected the the tangent distance to surface to be the distance from the centre of the polyhedra to the centre of the surface. Thus this distance should be shorter than the R values of the corresponding corner. *** Dump for solid - WCBarrelAnnulus *** =================================================== Solid type: G4Polyhedra Parameters: starting phi angle : 1.2 degrees ending phi angle : 361.2 degrees number of Z planes: 2 Z values: Z plane 0: -17285.5 Z plane 1: 17285.5 Tangent distances to inner surface (Rmin): Z plane 0: 16723.7 Z plane 1: 16723.7 Tangent distances to outer surface (Rmax): Z plane 0: 17083.7 Z plane 1: 17083.7 number of RZ points: 4 RZ values (corners): 16723.7, 17285.5 16723.7, -17285.5 17083.7, -17285.5 17083.7, 17285.5 Many Thanks Johannes
