The mate controller enables a user to interactively change order of positions of the model assembly which in turn affects order of position changes in motion studies of the model assembly. The mate controller saves per position data of the model assembly including mate values and component degrees of freedom. The saved per position data can be readily used to create animations.

Information regarding CAD model entities is accessed from a computer database, where the CAD model entities belong to one or more components of the subject CAD model. A graphical representation of the subject CAD model is presented to a user without loading bodies of the subject CAD model. The user is enabled to add a constraint between first and second entities of the subject CAD model, and information for the added constraint is stored with the subject CAD model in the computer database. Displaying the model in graphics mode saves time as well as memory usage, and the added constraints persistent after resolving the components from the graphics mode.
A common task when designing computer-aided design (CAD) assemblies is to ensure that the tolerances applied to each component are such that the assembly will function as expected when the parts are made to the extremes of their tolerance zones.

The instructions further cause the processor to create a derived layout sketch in the 3D environment associated with a first 3D part, where the derived layout sketch is a reference to or a copy of the 2D sketch, and automatically create a relationship between the first 3D part and a second 3D part where the relationship is based on a constraint between corresponding respective groupings of sketch entities.
A computer-implemented method automates motion of a computer-aided design (CAD) model. The CAD model represents a real-world object comprised of a number of parts. The part containing a user-specified entity is analyzed to collect data relevant to a motion study, for example, size data, location data, and material type data are collected. Based on the user-specified entity, parameters for automating motion are inferred and used to automate motion. The parameters include at least one of a part that is moved directly by a motor, a location on the part where the motor is mounted, a motor type, an axis of motion of the part, and a motion function indicating a change of motion over time.
Techniques for aiding user input with a graphical user interface (GUI) are disclosed. A target object among various command regions of the GUI is predicted, e.g., substantially before the cursor reaches any of the regions. The command region corresponding to the predicted target object is enlarged to facilitate user selection of the predicted target object. Enlarging the predicted target object may cause the target object to overlap and/or occlude nearby command regions. After a first target object is predicted, the prediction may be changed based on updated cursor movements. By using predictive target enlargement, users are given early visual feedback about the target, and are given a larger target to acquire, thereby allowing them to be faster and less precise (their mouse direction can wander) yet still acquire their desired result.

Automatic creation of fasteners for simulating a computer-aided design (CAD) model
A computer-implemented method and system automatically creates data for use by a computer-aided simulation process. The method and system determine that a CAD model component represents a real-world object that is a fastener. The method and system automatically analyze the CAD component and derive properties for use by the simulation process. The derived properties include size data, location data, and material type data. The method and system automatically calculate a zone of influence of the CAD component on another CAD component.

The invention method/product/data storage medium/system determines a location to place a new dimension annotation based on dimension type of the entity selected to annotate. One or more sets of existing dimension annotations are created. The existing dimension annotations in the same set together with the new dimension annotation with similar characteristics as those in the same set are sorted, and then displayed in sorted order in a view of the CAD model on the computer screen.
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.
Automatically adding constraints between entities in a subject computer-aided design (CAD) model of a real-world object includes storing information regarding CAD model entities and related constraints in a computer database in which the CAD model entities belong to one or more components of the subject CAD model or other CAD models. The computer database is accessed to determine previously used constraints for at least one entity of a given component being added to the CAD model, and constraints are automatically added between at least one entity of the given component and another entity in the subject CAD model based on the previously used constraints.

A computer-implemented method and system for rendering a computer-aided design model includes constructing a boundary representation data structure of the model comprising topological data for a face, constructing a data structure representing a parameter space of the face, and decomposing the parameter space into cells, where each cell indicates the presence of the face in the cell. The cells are encoded in a texture construct that is transmitted to a graphics processing unit where further processing renders the face on a computer monitor.

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.

Generating a routing system for a three-dimensional model of a real-world object includes specifying a set of connections, applying a filter to the connections to prevent more than one connection having the same first connector and the same second connector from being rendered more than once, creating geometric entities that are curves and that represent the connections, and displaying the routing system in a visually simplified manner by rendering the plurality of geometric entities. Additionally, the connections can automatically be merged into a harness bundle.
Updating a three-dimensional model includes generating a three-dimensional model comprised of components, modifying one of the components, determining other components having a possible changing effect on the three-dimensional model as a result of modifying the one component, and constructing a modified version of the three-dimensional model by regenerating the modified component and the other components having the possible changing effect while not regenerating remaining ones of the components not having the possible changing effect. The modified version achieves the same result as revising the three-dimensional model by regenerating each one of components.

Apparatuses and methods for automating the generation of additional different models of a mechanical object from a first model by logically partitioning the different models based on parameters that are specific to the particular model being generated. All of the models are independent representations of the same mechanical object, and may represent the design of the mechanical object in different phases of the manufacturing process, for example, the conceptual design, the as-cast design, and the as-machined design. In one embodiment, upon receiving a selection of a feature for the first conceptual model from a user, the apparatus and method can automatically calculate the corresponding contributions for each of the different models. The corresponding contributions can be automatically calculated based on modeling parameters that are specific to the type of model that is to be automatically generated.
