摘要: A method automatically propagates corner connection elements in a 3D modeled object having a plurality of corners with a plurality of structural corner-members. A list of the corners and a selection of a seed corner are received. A target corner in the model is identified as topologically similar to the seed corner. Reference data is collected for a first connection element at the seed corner. The first connection element reference data is copied and oriented to the target corner. A second connection element identical to the first connection element is created and applied to the target corner.

摘要: A computer-based method is disclosed of creating a visual representation of a threaded feature on a three-dimensional (3D) modelled object in a computer-aided design environment. The method includes constructing a helical curve and start and end circles for a threaded feature in a 3D modelled object, trimming the helical curve to conform to a geometry of the modelled object, identifying a boundary of the trimmed helical curve; and displaying a cosmetic thread to visually represent the threaded feature based on the trimmed helical curve and the identified boundaries of the trimmed helical curve.

摘要: A 3D modeled CAD object is flattened to a two dimensional 2D representation while maintaining a user selected wiring component represented in 3D. A user selected 3D component has a connector and a route segment with at least one stored sketch segment. A 3D and 2D tangent are calculated at a junction point of the route segment. A translation and rotation transformation is calculated to align the 2D and 3D tangents at the junction point. A calculated transformation matrix based on the translation and rotation transformation is used to display a flattened unconnected route segment aligned with the user selected 3D component.

摘要: A three dimensional (3D) backshell component is flattened to a two dimensional (2D) representation while maintaining a connected wiring component in 3D. Sketch segments for a curved 3D backshell connected first route segment within the backshell housing are stored. A first tangent is computed for a first entry point at a first end point of the connected first route segment, and a flattened route is calculated for route segments unconnected to the backshell. A flattened route position and a second tangent are calculated for a second route segment connected with the first route segment at a second entry point corresponding to the first entry point. The first entry point and the second entry point are aligned, and the first tangent and the second tangent are aligned, and the flattened unconnected route segment aligned with the 3D backshell component is displayed.

摘要: The invention notably relates to a computer-implemented method for designing a 3D modeled object by interaction of a user with a feature-based CAD system, the 3D modeled object representing a mechanical structure. The method comprises creating structural member features, each structural member feature representing a respective structural member of the mechanical structure, and displaying to the user a graphical representation of the mechanical structure based on the structural member features. The method further comprises creating corner features, each corner feature representing a respective corner of the mechanical structure, the creation of the corner features being performed automatically by the system, the corner features being editable by the user. This provides improved ergonomics for structural design.

摘要: Methods and systems identify frequently-used CAD components and apply machine learning techniques to predict mateable entities and corresponding mate types for those components to automatically add components to a CAD model. An example method includes accessing information regarding CAD model parts and related mate information stored in a computer database, and dividing parts into a plurality of clusters having parts with similar global shape signatures. In response to a new part being added, contextual signatures of entities of the new part are input into a mateability predictor neural network to determine a mateable entity of the new part. Input into a mate-type predictor neural network is (i) a contextual signature of the mateable entity and (ii) a contextual signature of an entity of another part of the CAD model to determine a mate type between the entities. A mate between the new part and the other part is automatically added based on the determined mate type.

摘要: Mating virtual objects in virtual reality environment, involves generating a bounding box having a plurality of faces corresponding to a plurality of exterior surfaces of a subject virtual object. A spatial mesh corresponding to surfaces of the real world environment is generated. A magnetic mate is generated to initially align a bounding box first face to a first spatial mesh surface. A shadow mate is provided between a bounding box second face and a second spatial mesh surface, by projecting a virtual ray from the subject virtual object bounding box second face toward the second spatial mesh surface, determining a mate point corresponding to an intersection of the virtual ray and the second spatial mesh surface, and displaying a mating button in the virtual reality environment at the mate point.

摘要: A computer-implemented method and system automatically adjusts the size of a selection area to aid in a selection of an object generated by a computerized system. The method and system detect a series of movements of a pointer, where the pointer is utilized to select an entity of the object. The series of movements are small and continuous. A set of entities that occupies the selection area is determined and the entities are analyzed for an indication of a level of difficulty in selecting one of the entities. The size of the selection area is reduced when the indication implies that the level of difficulty will be decreased after reducing the size of the selection area.

摘要: A computer-implemented method and system create computer-generated three-dimensional (3D) models in a broken state (broken view representation). To create a 3D model in a broken state, an area of the 3D model in an unbroken state is removed to create the 3D model in the broken state and a mapping between the 3D model in the unbroken state and the 3D model in a broken state is implemented to enable operations performed on the 3D model in the broken state to utilize data defining the 3D model in the unbroken state. The mapping maintains a relationship between data defining the 3D model in the unbroken state and data defining the 3D model in the broken state.

摘要: Editing features of a history-based computer-aided design (CAD) model may be difficult and may require redesigning much of the CAD model modify features. The solutions described herein allow a design engineer to modify an existing history-based CAD model by automatically determining history-based features that need to be converted to direct-edit features, creating a body of direct-edit features from the determined features, and creating a model containing both the direct-edit feature body and remaining history-based features. Such a CAD model containing both kinds of features may be referred to as a hybrid model.
