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.

Abstract: It is provided a computer-implemented method for designing a three-dimensional modeled object. The method comprises providing a boundary representation of the modeled object; determining a subset of the set of faces for which the faces are a copy one of another; forming a first group of faces within the subset that form a geometrical pattern; and associating to the first group of faces at least one second group of faces that are, for each face of the second group, adjacent to a respective face of the first group and that are, for each pair of faces of the second group, compliant with the rigid motion that transforms, one into the other, the respective faces of the first group to which the faces of the pair are adjacent. Such a method improves the design of a 3D modeled object.

Abstract: The invention notably relates to a computer-implemented method for querying a database. The database comprises 3D modeled objects that each represent a mechanical part. The database further comprises, for each 3D modeled object, a respective morphology signature. The method comprising: providing a query that includes a morphology criterion; returning, as results of the query, respective 3D modeled objects of the database, a respective 3D modeled object being returned based on an extent to which the respective 3D modeled object has a morphology signature that respects the morphology criterion. Such a method improves the field of searching mechanical parts in a database.

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: Described herein is a computer-implemented method for designing a three-dimensional modeled physical part. The method comprises providing a boundary representation of the modeled physical part, selecting, upon user action, a subset of the boundary representation that represents a geometric feature, identifying all the subsets of the boundary representation that are similar to the selected subset of the boundary representation by applying a feature similarity function.

Abstract: 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.

Abstract: It is provided a computer-implemented method for compressing a three-dimensional modeled object, wherein the method comprises providing a boundary representation of the modeled object; determining first data, that describe a mapping from the range of a reference function to the range of another function, and second data, that describe a mapping from the domain of the other function to the domain of the reference function which, when composed with the reference function and the mapping from the range of the reference function to the range of the other function, leads to the same result as applying the other function; and replacing in the geometrical data the other function by the first data, the second data and a pointer to the reference function. Such a method improves the compression of a 3D modeled object.
