Abstract: The invention notably relates to a computer-implemented method for querying a database that comprises 3D modeled objects that represent mechanical parts. The method comprises the steps of providing a query that includes a thickness criterion and returning, as results of the query, respective 3D modeled objects of the database based on an extent to which the respective 3D modeled object has a thickness that respects the thickness criterion. The thickness of the respective 3D modeled object is proxied by a thickness signature that corresponds to the evaluation of a function of the type ƒ(x)= a ( b + cx 3 2 ) . Such a method improves the querying of a database that comprises 3D modeled objects that represent mechanical parts.

Abstract: The invention notably relates to a computer-implemented method for designing a physical system constrained by a system of equations involving variables, the method comprising the steps of partitioning the variables involved in the equations into fixed variables and unfixed variables, thereby setting the system to a restricted system with a degree of freedom equal to 1, computing a parameterized curve of solutions of the restricted system in the domain of the unfixed variables, for at least one pair of unfixed variables, displaying the projection of the curve in the product of the domains of the pair, and navigating the solutions on the parameterized curve and representing, real-time, the current navigation position on the projection of the curve. Such a method improves the design of a physical system constrained by equations involving variables.

Abstract: 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.

Abstract: The invention notably relates to a method for determining specifications of the input of a manufacturing operation that outputs a part having cut-outs. The method comprises providing specifications of the output part, including a user-designed B-Rep having cycles of edges and modeling the part, the cut-outs being represented by the user with tunnels in the B-Rep, determining the set that consists of all cycles being the one having the smallest length in a respective equivalence class, performing a process on the set that includes iterating replacing a cycle when this reduces the length, and deleting a cycle when a sum results in a boundary cycle, otherwise replacing the cycle by the sum when this reduces the length.The invention offers an improved solution to detect, in a B-Rep having cycles of edges and modeling a part having cut-outs represented by tunnels, location of at least part of the tunnels.
