Abstract: A computer-implemented method of displaying a subset of a digitally modeled assembly (A) of objects (O1, O2, O3), the method comprising the steps of: a) generating and displaying a three-dimensional graphical representation of the assembly in a three-dimensional scene (3DSC); b) using a graphical tool (PT) for selecting one or more objects of said assembly from said three-dimensional graphical representation; c) determining a central point (CP) of the selected object or objects, and computing a distance of each object of the assembly from said central point; and d) modifying the displayed three-dimensional graphical representation of the assembly by hiding objects whose distance from the central point exceeds a threshold, or reducing their visibility. A computer program product, a non-transitory computer-readable data-storage medium and a Computer Aided Design system for carrying out such a method.

Abstract: The invention notably relates to a computer-implemented method for designing a 3D modeled object. The 3D modeled object is stored in a database. The method provides the 3D modeled object having a plurality of features; selects, upon user action, a first geometry of a first feature; queries and retrieves from the database at least one specification according to the selected first geometry. The method selects at least one second feature; and applies, on the selected at least one second feature, the specification retrieved from the database.

Abstract: A computer-aided design (CAD) system and corresponding method enable users to manage and share information related to a three-dimensional (3D) context of a 3D CAD model with ease. The method creates a 3D-link targeting the 3D context. The 3D-link includes a static link and a variable link. The static link re-directs to the variable link in response to a user opening the 3D-link. The variable link enables (i) the 3D CAD model to be located and opened and (ii) the 3D context to be displayed within the 3D CAD model. The method stores the 3D-link in a database. The 3D-link enables the 3D context to be shared between or among users via sharing of the 3D-link from the database. The 3D-link plays an important role in helping design engineers collaborate by eliminating the need to create pictures or copies of 3D models that may become outdated.

Abstract: The disclosed methods and systems allow adding constraints (“mates”) between components of the CAD model when in a graphics mode (i.e., when bodies of the CAD model are not loaded). Information regarding CAD model entities is accessed from a computer database, where the CAD model entities belong to one or more components of the subject CAD model. A graphical representation of the subject CAD model is presented to a user without loading bodies of the subject CAD model. The user is enabled to add a constraint between first and second entities of the subject CAD model, and information for the added constraint is stored with the subject CAD model in the computer database. Displaying the model in graphics mode saves time as well as memory usage, and the added constraints persistent after resolving the components from the graphics mode.

Abstract: A computer-implemented method for creating an animation summarizing a design process of a three-dimensional object, comprising the steps of: a) acquiring design data during at least one design session; b) automatically identifying time points of said session or sessions corresponding to milestones of the design process, and storing data representing statuses of the three-dimensional object at said milestones; and c) generating and displaying an animation of the design process, including displaying a graphical representation of a timeline (B) providing access to milestone data. A computer program product, non-transitory computer-readable data-storage medium and computer system for carrying out such a method.

Abstract: A method for locating a center of rotation of an articulated joint connecting two bones or set of bones of an upper or lower limb of a user, including performing a series of repetitive movements of sweeping one of the bones or set of bones around the joint, and simultaneously acquiring 3D positions of the bone or set of bones during said series, thereby obtaining a 3D cloud of points, computing a point referred to as center point, said center point being a searching point of the 3D searching space for which the standard deviation is the lowest considering the set of distances between the searching point and each point of the 3D cloud of points, transforming the 3D cloud of points into a plane, projecting the center point on said plane, thereby obtaining the center of rotation of the joint.

Abstract: A computer-implemented method for selecting a vertex among vertices of a 3D object in a 3D immersive environment of a CAD system where each vertex has a position in the 3D immersive environment including displaying the 3D object in the 3D immersive environment, detecting a hand gesture including opposing the pads of the index finger and the thumb, both pads being spaced, determining a segment parallel to a segment connecting the pads of the index finger and the thumb, the determined segment having a position in the 3D immersive environment, and identifying the vertex of the 3D object having the closest position with the determined segment.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for the generation and use of a fast battery model. One of the methods includes obtaining temperature data for one or more locations within or on the surface of a battery, the temperature data comprising time-varying heat flow inputs applied to the battery and time-varying temperature signals generated by the battery. The method also includes processing the temperature data to generate a continuous-time thermal model having one or more time-delay elements and one or more parameters, wherein parameter values are fitted using the temperature data.

Abstract: A computer-implemented method for civil engineering including obtaining a mesh representing a terrain and a polyline on the mesh, the method further includes computing a contributor of the polyline. The computing of the contributor includes modifying the mesh by determining, based on the polyline, a trench below the polyline. The computing of the contributor further includes computing a watershed segmentation of the terrain based on the modified mesh. The computing of the contributor further includes, based on the computed watershed segmentation, identifying, on the modified mesh, a basin comprising the trench. The contributor corresponds to the identified basin.
