Is there a way that I can make a solid out of the 2D Polyhedron?

If there is no solid, there is only one volume which is the whole space.

That's right and the outputs are garbage values, but I want to keep
those elements because they form part of a scene.

    I don't understand your question.
    If you don't have a "solid" some of the 9-intersection methods just
    don't make sense, do they?

        Hi,

        I am working with 3D Nef_Polyhedrons, I am creating these
        nef_polyhedrons from Polyhedron from OFF files. The probles is
        that some
        of these Nef_Polyhedrons do not have volume and create some
        problems in
        my analysis of the 9-intersection method.

        My questions are, how can I convert or use Polyhedron_3 and
        Nef_Polyhedron_2? Or How can I add some volume to my
        Nef_Polyhedrons_3
        whithout changing my OFF file? or in any case how can I create
        Nef_Polyhedrons_3 from 8 Points_3?

        Any help would be useful, thank you.

        Sincerely,

        Luis Rodriguez
