Patent number: 10303156Abstract: 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.Type: GrantFiled: December 6, 2016Date of Patent: May 28, 2019Assignee: DASSAULT SYSTEMESInventors: Jean-Francois Rameau, Remy Rorato

Patent number: 10303784Abstract: A computer-implemented method and system for querying a database that comprises 3D modeled objects that represent mechanical parts. The method or system provides a query that includes a likeness criterion relative to the value of a predetermined shape descriptor for an input 3D modeled object. A next step returns, as results of the query, respective 3D modeled objects of the database based on an extent to which the value of the predetermined shape descriptor for the respective 3D modeled object respects the likeness criterion. The value of the predetermined shape descriptor for a respective 3D modeled object includes a set of axis systems that are trihedral. The likeness increasingly depends on an extent to which sets of axis systems match each other modulo a same similarity transformation. Such a method and system improves the querying of a database that comprises 3D modeled objects that represent mechanical parts.Type: GrantFiled: May 20, 2016Date of Patent: May 28, 2019Assignee: Dassault SystemesInventor: Remy Rorato

Patent number: 10198488Abstract: 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.Type: GrantFiled: May 23, 2016Date of Patent: February 5, 2019Assignee: Dassault SystemesInventors: Laurent Marini, Remy Rorato, Jean-Francois Rameau
