Abstract: A system and method for rendering a three-dimensional object as clipped based on one or more clipping shapes. A three-dimensional space is partitioned based on the clipping shapes to determine a clipped volume domain having an envelope of faces. The envelope is projected onto a screen plane according to a first viewpoint. The three-dimensional modeled object is rendered as a clipped three-dimensional modeled object based on a determination, according to each pixel on the screen plane with respect to the first viewpoint, of which faces of the envelope are projected onto each pixel. Rendering can then be repeated any time the viewpoint is changed without requiring further data preparation.

Abstract: A process updates a status of relation between objects in a system of computer-aided design, for subsequent analysis of status of relation. The process identifies a set of data of a group of objects, preferably a pair of objects; a method of computation of relations between objects; and an expected relation of executing the method identified using the set. Next the process executes the method using the set of data to compute a relation. A comparison step compares the expected relation with the computed relation. The process updates a status of the expected relation based on a result of the comparing step.

Abstract: A system for tolerancing geometrical templates upgrades the geometrical template to include a unique identifier and index corresponding to each sub-feature of the template. The upgraded template is associated to a set of 3D annotations and the association is stored in a catalog which uses the unique identifier as an index. Upon instantiation of the geometrical template, a list of corresponding tolerance templates are retrieved and displayed for selection, and a selected tolerance template is then instantiated onto the geometrical template.

Abstract: A computer-implemented method includes creating a video record of user interactions with a computer program, and displaying a control area configured to receive a rewind user command and an advance user command. In response to receiving the rewind user command, the computer program reverts to a first state that is prior to at least one of the recorded user interactions. In response to receiving the advance user command, the computer program progresses to a second state that is between the first state and a last-known state of the computer program.

Abstract: A computer-implemented method for verifying a model in a product lifecycle management (PLM) system includes defining a model and an envelope of allowable model states and, based on one or more requirements, deriving at least one counterexample objective. The method also includes optimizing a set of parameters related to the allowable model states and the allowable model context, redefining at least one of the model and the allowable model states when the at least one counterexample objective is outside of a specified tolerance, and, after a predefined number of iterations, defining the model as verified.

Abstract: This invention is directed to a method, a program and a production edition system of visualization of objects in a scene. The method according to the invention aims at indicating a distance between objects by modifying a property (like a rendering property) of a target object according to a distance to an active object. Typically, a light source is simulated and attached at the active object and the scene is accordingly modified dynamically. Such a method bypasses the basic materialization of the distance between objects. Hence, no display of extrinsic elements is mandatory and possible interferences are prevented. In addition, the method allows, by definition, a progressive modification of e.g. a rendering of the target object. Thus, modifications in the scene are better understood by the user and ergonomics are improved.

The modeled object to be updated is modeled with a directed acyclic graph having at least one path. The path is formed of nodes and arcs, where: (i) each node represents a modeled object, and (ii) each arc represents the use of a respective end node by a corresponding origin node.

Next the invention method and system compute from the first path, a second path of nodes impacting the update of the modeled object to be updated. In turn, the invention method and system update the modeled object to be updated by using the nodes of the second path. The invention also provides a computerized system, such as a Product Lifecycle Management (PLM) system, comprising program code means for carrying out the method of the present invention.

Abstract: A computer system and method provides access to Web (global computer network) services data of a target system. The target system exposes data through multiple web services. An application interface is adapted to interface with the target system re-using existing (predefined) web services among applications for the target system. The application interface queries the exposed data. A mapping member maps between application interface query of exposed data and syntax of objects useable in a subject application. The mapping member enables the subject application to access data of object instances generated in response to the query.
