In an embodiment, a computer-implemented method of creating a 3D-part within a computer aided design (CAD) three-dimensional (3D)-assembly can include, in the CAD 3D-assembly, creating the 3D-part based on user input received in the 3D assembly. The method can further include automatically associating a history with the created 3D-part, the history based on the user input used to create the 3D-part.

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.

A computer-implemented method and system reduces size of a data structure of a computer-aided design (CAD) model. Given a CAD model formed of a plurality of modeling elements, the method and system provide one or more geometric entities defining modeling elements of the CAD model. The geometric entities have corresponding graphical entities configured to display the CAD model. For each modeling element, the method and system determine visibility of the modeling element and produce a reduced data structure by storing in the structure graphic data representing the graphical entities and geometric data of only certain ones of the geometric entities determined as a function of visibility of the corresponding modeling elements.

Reducing the size of a model using visibility factors

Creating a reference to data used to construct a computer-aided design model includes storing model data with tracking data, where the tracking data identifies the model data. A reference is created and the tracking data is associated with the reference to enable the reference to refer to the model data. A modeling operation is executed, which retrieves the tracking data associated with the reference, traverses a data structure defining the computer-aided design model while attempting to match the tracking data associated with the reference to the tracking data stored with the model data, and returns geometric data stored in the model data.
