Hello, I'm using G4BREPSolidPolyhedra to model a hollowed prism with an hexagonal base (nSides=6, rMin,rMax>0). Several of these solids (with the same shape, and different radiuses) must be embedded inside each other. Unfortunately, I cannot use mother-daughter relationships because of a complex hole in the middle of the detector. I'm using a big World volume where I'm embedding all the objects. Unfortunately, the boundaries of several solids (all children of World) are touching themselves. Does this count as a geometry violation ? The ugly solution is to use a small gap between each solid. Is there another way ? The example TestEm03 seems to have several rings in this configuration and there aren't any problems.

Is there a way out of there ?

Thanks,

Denis Rosset
