Abstract: The invention notably relates to a computer-implemented method for designing a mechanical part, the method comprising: providing a subset of a finite element mesh (FEM), the subset of the FEM representing the mechanical part; and determining a representation of a skeleton of the mechanical part based on the subset of the FEM, the skeleton having branches and branch junctions, each branch junction joining respective branches. This improves the designing of a mechanical part.

Abstract: A computer-implemented method and system create computer-generated three-dimensional (3D) models in a broken state (broken view representation). To create a 3D model in a broken state, an area of the 3D model in an unbroken state is removed to create the 3D model in the broken state and a mapping between the 3D model in the unbroken state and the 3D model in a broken state is implemented to enable operations performed on the 3D model in the broken state to utilize data defining the 3D model in the unbroken state. The mapping maintains a relationship between data defining the 3D model in the unbroken state and data defining the 3D model in the broken state.

Abstract: A computer-implemented method for designing a virtual garment or upholstery (G) in a three-dimensional scene comprising the steps of: a) providing a three-dimensional avatar (AV) in the three-dimensional scene; b) providing at least one pattern (P) of said virtual garment or upholstery in the three-dimensional scene; c) determining a distance field from a surface of the avatar; d) positioning the pattern relative to the avatar by keeping a fixed orientation with respect to said distance field; and e) assembling the positioned pattern or patterns around the avatar to form said virtual garment or upholstery, and draping it onto the avatar. A computer program product, non-volatile computer-readable data-storage medium and Computer Aided Design system for carrying out such a method. Application of the method to the manufacturing of a garment or upholstery.

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: Embodiments of the present invention simulate a real-world system by first generating a time dependent system of equations that represents the real-world system where the time dependent system of equations has a defined constraint. Next, the constraint is de-coupled from the time-dependent system of equations using a matrix representing an approximation of physics of the real-world system, the de-coupling generating a first system of equations representing the constraint and a second system of equations representing physics of the real-world system. In turn, the generated first and second systems of equations are solved and the real-world system is automatically simulated by generating a simulation using results from solving the first and second systems of equations.

Abstract: A computer-implemented method for designing an industrial product modeled with a binary tree having leaf nodes representing basic volumes, non-leaf nodes representing binary commutative operation combining volumes, the method comprising the steps of: performing a design operation triggering the adding or the removing of a leaf node; and idealizing the binary tree, i.e. modifying the binary tree while maintaining the optimality of the tree by minimizing the number of weak leaf nodes, a weak leaf node being a leaf node such that, when removed, the resulting binary tree is not optimal anymore.

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: A computer implemented method for designing a 3D modeled object that represents a mechanical part. The method comprises selecting a group of faces of the B-Rep, defining a trajectory for each respective face of the group of faces, computing, for each face of the group of faces, a respective swept volume, the swept volume corresponding to the volume swept by the respective face with respect to the trajectory, assigning a material removal label or a material adding label to each swept volume, according to the position of the swept volume at the respective face with respect to the interior of the 3D modeled object, and updating the B-Rep with a material removal volume and then a material adding volume. The method improves the design of a 3D modeled object.

Abstract: It is provided a computer-implemented method for designing a folded sheet object, comprising the steps of providing (S10) panels separated by bend lines, including at least four adjacent panels forming a cycle and separated by concurrent bend lines, with predetermined angles between successive bend lines; and determining (S20) a control law linking the angles between the adjacent panels of the cycle, as a function of the predetermined angles between successive bend lines. Such a method improves the design of a folded sheet object.
