Abstract: A method automatically propagates a corner trimming in a 3D modeled object having a plurality of corners with a plurality of structural corner-members. Each corner includes a corner location and a count of its corner-members. The features of each corner-member include a cross-sectional shape and size, a corner-member location, and its relative orientation with respect to the other corner-members. A list of the corners and a selection of a seed corner is received. A target corner in the model is identified as topologically similar to the seed corner. A user definition of a trimming of the seed corner is automatically applied to the target corner.

Abstract: 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.

Abstract: 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.

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 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.
