CreateSweptBRep3D(...)
    CreateSweptBRep3D( (object)profile, (object)path, (bool)railrotation, (Vector3D)rotAxis) -> tuple :
        Create BRep3D by means of a vector of profiles extrusion along a path
        
        Parameter: profile       profiles to extrude, if closed solid will be created, otherwise a surface only
                   path          path to extrude along
                   railrotation  if true, rotate profile along the path
                   rotAxis       if set, profile will be rotated along this axis along the path
