You probably have an face orientation issue.
You can try calling orient_polygon_soup()

http://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__repairing__grp.html#gaadc5bac3072b11d2313e40043c729d0a

Note that in case of non-manifold vertices, those will be duplicated.

ah! you are right, it is not valid..
So probably  there is something wrong with the way i build it?

I use the following code to build it:

using Kernel=CGAL::Exact_predicates_inexact_constructions_kernel;
using CGALPolyhedron=CGAL::Polyhedron_3<Kernel>;
using HalfedgeDS=CGALPolyhedron::HalfedgeDS;

template<class HDS>
class  PolyhedronBuilder:public CGAL::Modifier_base<HDS>
{
public:


    Mesh         M;

    PolyhedronBuilder(){}
    explicit PolyhedronBuilder(const Mesh& model):M{model}{}
    void operator()(HDS& hds)
    {
        typedef typename HDS::Vertex    Vertex;
        typedef typename Vertex::Point     Point;

        CGAL::Polyhedron_incremental_builder_3<HDS> B(hds,true);
        B.begin_surface(M.vertices.size(),M.indices.size()/3);

        //add vertices
        for(const auto& vert:M.vertices)

B.add_vertex(Point(vert.Position.x,vert.Position.y,vert.Position.z));

        //add faces
        for(uint i=0;i<M.indices.size()/3;i+=3)
        {
            B.begin_facet();
            B.add_vertex_to_facet(M.indices[i]);
            B.add_vertex_to_facet(M.indices[i+1]);
            B.add_vertex_to_facet(M.indices[i+2]);
            B.end_facet();
        }
        B.end_surface();

    }
};

and then:
PolyhedronBuilder<HalfedgeDS> builder(mesh);
myPolyhedron.delegate(builder);

which was based on
<http://doc.cgal.org/latest/Polyhedron/classCGAL_1_1Polyhedron__incremental__builder__3.html>
.

                                A writable property map, as describe in the
                    concept of the
                            boost web
                                site is a mecanism that allow to generically
                    associate a
                            property
                                (the value type) to a given object (the
        key).

                                If you want to associate a normal to a
        facet of a
                            Polyhedron, here
                                is a simple example (not tested):


                                struct Poly_normal_map{

                                  typedef Polyhedron::Facet_handle key_type;
                                  typedef Kernel::Vector_3 value_type;
                                  typedef

                                  Poly_normal_map() : normals(NULL)
                                  {}


        Poly_normal_map(std::map<Polyhedron::Facet_handle,

         Kernel::Vector_3>& n)
                                    : normals(*n)
                                  {}

                                  friend void put(Poly_normal_map pnm,

        Polyhedron::Facet_handle fh,
                                                  const Kernel::Vector_3& n
                                  {
                                    CGAL_assertion(pnm.normals!=0);
                                    pnm.normals.insert(
        std::make_pair(fh, n) );
                                  }
                                };

                                std::map<Polyhedron::Facet_handle,
                    Kernel::Vector_3> normals;
                                Poly_normal_map vpm(normals); //vpm is you
                    writable property map


                                If you want to make the property map
        read-write,
                    you can add
                                a get function:

                                  friend const value_type&
        get(Poly_normal_map pnm,

                     Polyhedron::Facet_handle fh)
                                  {
                                    CGAL_assertion(pnm.normals!=0);
                                    return pnm.normals[fh];
                                  }

                                and update the category tag.

                                Note that the code I've written is roughly
                    equivalent to using a
                                boost::associative_property_map

                                    doing exactly what I want . In the above
                    link I found
                            out that the
                                    second argument was of type
        VertexNormalMap
                    which is a
                            model of
                                    WritablePropertyMap. There was a link

                                    to boost libraries explaining(?) what
                    writable property
                            map is .

                                    Unfortunately this is my first encounter
                    with property
                            maps and
                                    consequently I am a bit confused..
                                    I also had a look at cgal's
        explanation of
                    property maps
                            page

                                    did not
                                    understand much..

                                    Could anyone suggest a way of
        creating the
                    property map
                            I need?

                                    Best Regards,
                                    Iason
