I did use setf(std::ios::scientific) and precision(20) to set the format. Here is a snapshot:

    std::ofstream SaveFile(fileName);
   CGAL::set_binary_mode(SaveFile);    
   SaveFile.setf(std::ios::scientific);
   SaveFile.precision(20);
   SaveFile << polyhedron;
   SaveFile.close();


Is it possible that this causes all the trouble? Is there any CGAL specific statements that can do the same thing?

Thanks.

Joe

That way my only idea.

I agree that your ascii file is OK. But your binary file is not.

I am not sure that there is CGAL operator>>Polyhedron. Your binary file is
corrupted, but I cannot know why.
