The author has considered three quadratic forms (i) ƒ = Gaβduaduβ (ii) θ = μaβduaduβ and (iii) Φ — ξaβduaduβ. With the help of these quadratic forms ten distinct families of ruled surfaces have been obtained. The intersection of these ruled surfaces with the surface of reference yields interesting results. Also, some particular cases have been studied.

ITA Progettare un modello origami significa passare dalla riflessione sulla pura forma di un oggetto alla sua realizzazione nel modello in carta. Modellare in origami produce modelli dinamici, dal singolo foglio di carta alla realizzazione di una forma tridimensionale e il procedimento, oltre a non alterare il materiale, è reversibile. | ENG Designing
