PROBLEM TO BE SOLVED: To provide a computer-implemented method for designing a three-dimensional modeled object.SOLUTION: The method comprises providing a modeling graph having nodes that represent geometrical objects and arcs that each represent a relationship linking two geometrical objects represented by incident nodes of the arc, in which procedural relationships are represented by unidirectional arcs having the same orientation as the procedural relationships, and the relationships further include live relationships that are represented by bidirectional arcs. The method also comprises: upon a modification of data defining a 3D modeled object, determining a strong graph, where the strong graph is the graph of strong components of the modeling graph; and updating the 3D modeled object according to a traversal of the strong graph. Such a method improves the design of the 3D modeled object.SELECTED DRAWING: Figure 1 |
