Abstract: It is proposed a computer-implemented method for designing an assembly of parts in a three-dimensional scene. The method comprises: providing at least a first part and a second part, the parts being stored in a database; for each part: (i) querying in the database for one or more constraints applied to the part; (ii) retrieving in the database geometries on which constraints are applied; computing at least one relative position of the first part and the second part by using the retrieved geometries.

Abstract: The invention is directed to a method for designing an assembly of objects in a system of computer-aided design, the method comprising: (i) selecting a first object and a second object of the assembly, each of the first object and the second object having interface information; (ii) computing a set of positions of the first object relatively to the second object of the assembly; and (ii) displaying simultaneously representations of the computed positions of the first object relatively to the second object.

Abstract: The present invention provides a computer implemented method for editing a product. The product comprises three-dimensional modeled objects. The method comprises the step of displaying a three-dimensional representation of a hierarchy of the three-dimensional modeled objects. The three-dimensional modeled objects are displayed three-dimensionally in the representation. The method further comprises the step of selecting at least one of the displayed three-dimensional modeled objects. The method further comprises the step of performing an action on the selected object. The hierarchy is edited upon the performing of the action.

Abstract: The invention has for object a computer-implemented method of designing a product, the product being composed of an assembly of components organised hierarchically in a product tree, the method comprising the steps of: initially selecting a component; determining a path comprising the product tree's components located between the root of the product tree and the initially selected component; navigating through this path by using a scrolling mean in order to choose a candidate component among the path's components; selecting the said candidate component as a perimeter of design action PDA component; activating at least a functionality required for modifying the component defined as the perimeter of design action.

Abstract: An embodiment of a method for designing an assembly of objects in a system of computer-aided design can include:(i) selecting a first object and a second object of the assembly, each of the first object and the second object having interface information; (ii) computing a set of positions of the first object relatively to the second object of the assembly, and (iii) displaying simultaneously representations of the computed positions of the first object relatively to the second object.

Abstract: In one embodiment, a method for designing an assembly of objects in a system of computer-aided design includes selecting a first object and a second object of the assembly. The method can further include computing a set of relative positions between the first object and the second object of the assembly, ranking the relative positions of the set between the first object and the second object according to at least one criterion, and providing the best of the relative positions between the first object and the second object according to the ranking step.

Abstract: The invention is directed to a Product Lifecycle Management (PLM) update process for updating objects with respect to specifications. The process invokes dependence relations between objects. It relies on building a directed graph, wherein objects are the nodes of the graph. An arc (also called “edge”) is directed from a second object to a first object, the latter depending on the second object according to dependence relations of the PLM system. Thus, the update can be carried by browsing the graph along the direction of the arcs in the graph. Owing to the reversion of the graph with respect to the dependence of objects, the simple solution of the invention guarantees that the update of an object occurs only when the ancestor object it depends on is up to date, and so on. This drastically reduces failures at update in practice.
