Hi I have a class derived from Polyhedron_3 class. Now I have a problem in
access it.

This is an simple example

typedef CGAL::Simple_cartesian<double> Kernel;
typedef Kernel::Point_3  Point_3;
typedef CGAL::Polyhedron_3<Kernel>     Polyhedron;
typedef Polyhedron::Vertex_iterator        Vertex_iterator;

class Model : public Polyhedron{
  int A;        
public:
   Model(char *FileIn){
         A=254;
         std::ifstream FIN(FileIn);
         std::ofstream FOUT("cube28_.wrl");

         std::cout << "ops";
         // all guives me error
         FIN >> this->Polyhedron_3;
         FIN >> this->Polyhedron;

   }

};

int main() {

  Polyhedron P;
  Model M("cube26.ply");
  std::ifstream 
fcin("C:\\Users\\rlam\\Desktop\\CGAL\\Polyhedron\\cube26.off");
  std::ofstream
fcout("C:\\Users\\rlam\\Desktop\\CGAL\\Polyhedron\\cube26.wrl");
    fcin >> P;
    CGAL::VRML_2_ostream out( fcout);

}
