Abstract: Described is a computer-implemented method for learning a function configured for reconstructing, for a class of real objects, a 3D modeled object that represents an instance of the class from a depth map of the instance. The method comprises providing a parametric model of the class, creating a database, and learning the function with the database. The method improves the 3D reconstruction of a real object from a depth map.

Abstract: A computer-implemented method and system creates a multi-element feature in a three-dimensional (3D) computer-aided design (CAD) model. A first element and a second element are selected to include in the multi-element feature. A single sketch is created comprised of sketch entities, a subset of which defines the first element and another subset of which defines the second element. A connection entity is included in the single sketch. The connection entity joins the first and the second elements. A modeling operation applied to the single sketch creates the multi-element feature.

Abstract: A computer-implemented method for creating a set of bounding boxes on a three-dimensional modeled assembly in a three-dimensional scene. The method comprises providing three-dimensional modeled objects forming a three-dimensional modeled assembly in a three-dimensional scene; computing a main bounding box encompassing the three-dimensional modeled assembly, creating a set of three-dimensional modeled objects that meet at least one property of the three-dimensional modeled assembly, computing two or more bounding boxes encompassed by the main bounding box, one of the two or more bounding boxes comprising the three-dimensional modeled objects of the set.

Abstract: Described herein is a computer-implemented method for orienting 3D printing of a real object. The method comprises obtaining a 3D modeled object that represents the real object. The method also comprises determining one or more orientations of the 3D modeled object for which an overhang volume is optimal. This improves 3D printing.

Abstract: A computer-implemented method and system provide one or more primitive commands. Each primitive command when executed defines a shape of an object and accepts input data to specify one or more dimensions of the shape. When the dimensions are applied to the shape, a three-dimensional (3D) object that is a 3D part and/or a 3D feature is created. Input data is utilized by a selected primitive command to create a sketch as specified by a definition of the shape on a sketch plane that is automatically selected and to specify a transformation that creates the 3D object from the sketch.

Abstract: A computer-implemented method and system of computer-aided design products for dynamically manipulating an assembly of objects in a three-dimensional scene. The system and method provide the assembly of objects with information relative to kinematic joints linking objects of the assembly. The system and method provide a dynamic manipulating tool (DM) embedded in the scene. The DM tool includes a reference with three-axes allowing for each axis a degree of freedom in translation and a degree of freedom in rotation. Next the system and method attach said dynamic manipulating tool (DM) to one object of the assembly, and select a degree of freedom of the dynamic manipulating tool (DM) attached to the object of the assembly. The system/method apply a load according to said selected degree of freedom and calculates and displays in real-time the result of a dynamic simulation of said load applying.

Abstract: The invention notably relates to a computer-implemented method for compressing data representing values of a physical attribute in a predetermined space. The method comprises providing a signal that includes a mapping from leaf cells of a hierarchical subdivision of the predetermined space each onto a respective coefficient representative of a value of the physical attribute at the respective leaf cell. The method also comprises determining a discrete wavelet transform of the signal and encoding the determined discrete wavelet transform. The method provides an improved way to compress a modeled object that represents a real object.

Abstract: A 3D CAD model of a plant, a factory, refinery, or facility is re-built from laser scan data of the plant, a factory, refinery, or facility. Through a rules-based analysis, CAD model objects are identified in the laser scan data. The rules map laser scan data to CAD model objects based on shape, size and/or sequence of connection of objects in the plant, a factory, refinery, or facility grouping. Design logic of equipment and process facilities are also utilized by the rules.

Abstract: Computer method and apparatus in a PLM system defines completeness of an end-item set for a given product demand set. The BOM for the product demand set is represented in a tree-based graph structure. Completeness of end-items is determined and/or validated such that one can build the target product set from the set of end-items. Shared items, parts and subassemblies of the given product are taken into account.

Abstract: It is provided a computer-implemented method designing a three-dimensional modeled object, comprising the steps of providing (S10) a plurality of two-dimensional views of the modeled object, a three-dimensional wireframe graph, associating (S20), to each vertex of the wireframe graph, a local radial order between all the edges incident to the vertex, and then determining (S30) edge cycles, by browsing the wireframe graph following the local radial orders associated to the vertices. Such a method improves the design of a 3D modeled object.
