Designing industrial products by using geometries connected by geometrical constraints

摘要

The invention notably relates to a computer-implemented method of design of an industrial product wherein constraints between geometries of the industrial product are modeled with a graph of constraints comprising nodes and edges, a node representing a geometry and an edge representing a constraint between two geometries. The method comprising the steps of selecting at least one geometry of the product; computing a depth value of each node of the graph from a node representing the at least one selected geometry; identifying antagonistic constraint(s) in the graph, an antagonistic constraint being represented by an oriented edge wherein the depth value of the start node is larger to the depth value of the end node; reversing the identified antagonistic constraint(s); modifying the at least one selected geometry;
