The disclosure notably relates to a computer-implemented method of assembling parts of a product. The method comprises building a non-hierarchical graph from at least one products, the graph comprising nodes and edges between nodes, a node representing a part of the product to be assembled and an edge representing a relationship between a pair of parts represented by nodes, providing a part of the product to be completed, performing, upon user action, a selection on the provided part, identifying in the graph a node representing the selected part and one or more nodes that have the closest relationships to the node representing the selected part.

Method of assembling parts of a product

A computer-implemented method for classifying three-dimensional (3D) objects including obtaining a set of 3D objects. Each 3D object of the set has a signature representative of the morphology of the 3D object. The method also includes computing a multi-level clustering of the set of 3D objects. The multi-level clustering is a hierarchical tree structure of clusters of 3D objects of the set and has N hierarchical levels. The method also includes selecting, automatically or upon user interaction, one of the computed clusters of a level of the multi-level clustering thereby defining a current level. The method comprises displaying, to a user, 3D objects of the selected cluster in a first part of a display. The method further includes classifying, upon user interaction, the displayed 3D objects. The computer-implemented method improves the classification of 3D objects.

3D clustering navigation

This invention is directed to a process, computer program and apparatus for displaying an assembly of objects of a product lifecycle management database. The method according to the invention aims at providing an access to the database, selecting the assembly of objects in the database, identifying a plurality of viewpoints on said assembly, retrieving from the database a set of objects of said assembly according to the plurality of identified viewpoints, computing a model of said assembly for all the retrieved objects of the set of objects, and displaying a view of the model, any displayed views being computed locally starting from the objects retrieved at the retrieving step.

Process, program and apparatus for displaying an assembly of objects of a PLM database

The invention is directed to a process, an apparatus and a program for selecting objects in a PLM database containing modeled objects. The invention allows a user to rapidly display a view of the set of objects while allowing for selecting objects in the view, without the need for loading the complete and exact representations of all the objects of the view when the user is looking for particular objects to work on.

Process for selecting objects in a PLM database and apparatus implementing this process

The invention proposes a process for rendering an object view using a PLM database. The database comprises modeled objects and relations between said modeled objects. Said modeled objects are associated to a set of values of attributes, whose values are stored in the database or computable based on relations involving said modeled objects. The process comprises displaying to the user a view of a set of modeled objects; receiving a selection by a user of an attribute; querying the database for a modeled object to be rendered; providing a value of the selected attribute, associated to said modeled object; and rendering said modeled object in the view according to the provided value of the attribute. It is also possible for the user to select a value of an attribute and the rendering will be carried out only on the object, whose value(s) matches with the selected value.

Process and system for rendering an object in a view using a product lifecycle management database

The invention is directed to a method for designing a modeled object within a session of CAD system interacting with a database. The method comprises:

Designing a modeled object within a session of a computer-aided design system interacting with a database

The invention is directed to an apparatus, a computer program and a process for displaying objects of a PLM database, including the steps of providing a PLM database containing modeled objects and a graphical user interface (), identifying (S) a viewpoint on a view () of objects (-) to be rendered; and rendering (S-) said view according to the viewpoint, wherein the step of rendering includes determining (S) a plurality of locations (-) in the view, searching the database and identifying therein modeled objects according to the determined locations, and incrementally displaying (S-S) in the graphical user interface the modeled objects identified so as to rendering said view.

Process for displaying objects of a PLM database and apparatus implementing this process

A relational database contains a set of data and relations between the data of the set. The data may be representative of three dimensional modeled objects. For navigating in the database, the user selects a first data and a first relation; the second data related to the first data according to the first relation are searched. Then, a three-dimensional representation of objects represented by the second data is displayed to the user. When the user selects one of the displayed objects and a second relation, the second data representative of the selected object is identified. Then, third data related to the identified second data according to the second relation are found. A three-dimensional representation of objects represented by the third data is then displayed. The user may navigate in three-dimensional representations of the objects represented in the database, without any need to know and understand the structure of the database.

Graphical method for navigating in a database of modeled objects

The invention is directed to a product life cycle management (PLM) system, comprising a database storing objects, preferably 3D objects, and relations between said objects. The PLM system provides a graphical user interface suitable for displaying to a user a graphical representation of a hierarchy of stored objects. The graphical user interface is adapted, upon selection of a displayed object by a user, to display objects related to the selected object. At a given level in the hierarchy, displayed objects are distributed according to a respective weight. The weight of a displayed object depends on the number of its descendants in the hierarchy, which are displayed in said graphical representation. The invention makes it possible to navigate in a database of a PLM system, storing notably complex modeled objects through interrelated data. Thanks to the principle of the weight dependence discussed above, the solution further allows the user to comprehend its progression through the organized data as well as the relations between objects and this, in an easy and intuitive way.

Method and system for graphically navigating among stored objects

The invention is directed to a process, an apparatus and a program for selecting an object in a PLM database containing modeled objects. The invention allows a user to rapidly display a view of the set of objects while allowing for selecting an object in the view, for example through movement of a pointer such as a mouse.
