Dear Zhiyi, Unfortunately it is quite hard to use G4BREPSolid directly - I would not recommend it. I would suggest to examine whether an existing solid (or a boolean operation on a set of existing solids) could be used to yield the solid you need or an approximation to it which is adequate. What is certain is that neither this solid nor any other in Geant4 is able to infer information - for example to determine by itself how to create some surfaces. If you described what you want to do, maybe we can offer further advice.
