Hi,
In my application I'm using the skeleton/offset structures to draw the 
complete skeleton like straight_skeleton_2 demo.

I save the skeleton points this way:

template<class K>
void print_file_straight_skeleton(std::ofstream& file_out, 
CGAL::Straight_skeleton_2<K> const& ss)
{
 typedef CGAL::Straight_skeleton_2<K> Ss ;
 typedef typename Ss::Vertex_const_handle     Vertex_const_handle ;
 typedef typename Ss::Halfedge_const_handle   Halfedge_const_handle ;
 typedef typename Ss::Halfedge_const_iterator Halfedge_const_iterator ;

 Halfedge_const_handle null_halfedge ;
 Vertex_const_handle   null_vertex ;
 
 for ( Halfedge_const_iterator i = ss.halfedges_begin(); i != 
ss.halfedges_end(); i++, i++)
 { 
   print_file_point(file_out, i->vertex()->point());
   file_out << std::endl ;
 }
}

What's the best way to draw skeleton?

Regards.
