Unfortunately I could not reproduce the pb. All the models you gave are
working correctly on my computer ( I tried with CGAL 4.14 and the master
branch).

Could you please tell us more about your platform (OS, compiler, ...)? what versions of CGAL and Eigen are you using?

If you can compile in debug and run at least one case in the debugger,
it might help to provide the call stack.

Thanks,

Sebastien.

Dear Sebastian,

Thank you for your replying. As your suggestion, I change /typedef
CGAL::Simple_cartesian<double> Kernel;/ to /typedef
CGAL::Exact_predicates_inexact_constructions_kernel Kernel;/

Unfortunately, the same issue still appears. I tested four different .off
files provided by CGAL examples and here is their testing result.

hand.off <http://cgal-discuss.949826.n4.nabble.com/file/t376145/hand.off> :

knot.off <http://cgal-discuss.949826.n4.nabble.com/file/t376145/knot.off> :

Once again, thank you for your help!
