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.

1. A computer-implemented method of designing 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:
selecting at least one geometry of the industrial product; computing a depth value of each node of the graph from a node representing the at least one selected geometry; identifying one or more antagonistic constraint in the graph, each antagonistic constraint being represented by an oriented edge wherein a depth value of a start node of the oriented edge is larger relative to a depth value of an end node of the oriented edge; reversing the identified one or more antagonistic constraint; modifying the at least one selected geometry; and propagating the modification of the selected geometry.
