Abstract: It is provided a computer-implemented method designing a three-dimensional modeled object, comprising the steps of providing (S10) a plurality of two-dimensional views of the modeled object, a three-dimensional wireframe graph, associating (S20), to each vertex of the wireframe graph, a local radial order between all the edges incident to the vertex, and then determining (S30) edge cycles, by browsing the wireframe graph following the local radial orders associated to the vertices. Such a method improves the design of a 3D modeled object.
