摘要： A computer-aided design (CAD) system and corresponding method enable users to manage and share information related to a three-dimensional (3D) context of a 3D CAD model with ease. The method creates a 3D-link targeting the 3D context. The 3D-link includes a static link and a variable link. The static link re-directs to the variable link in response to a user opening the 3D-link. The variable link enables (i) the 3D CAD model to be located and opened and (ii) the 3D context to be displayed within the 3D CAD model. The method stores the 3D-link in a database. The 3D-link enables the 3D context to be shared between or among users via sharing of the 3D-link from the database. The 3D-link plays an important role in helping design engineers collaborate by eliminating the need to create pictures or copies of 3D models that may become outdated.

摘要： The disclosed methods and systems allow adding constraints (“mates”) between components of the CAD model when in a graphics mode (i.e., when bodies of the CAD model are not loaded). 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.

摘要： A method for selecting a plurality of edges or faces of a displayed modeled object in a computer-aided design (CAD) system extracts a plurality of features, each feature including a measurable numeric property of one or more of edges or faces of the modeled object. The features are scaled, and a selection of a seed edge or a seed face is received. A suggested edge or face is chosen based upon the seed edge or seed face, and a graphical indication of the suggested edge or face is displayed on the modeled object.

摘要： A change in orientation or reorientation operation is applied to 3D models while maintaining constant zoom level of model display. The orientation is provided by a computer-based tool or GUI widget formed of a transparent container element and a miniaturized depiction of the 3D model. The transparent container element encapsulates the miniaturized depiction and enables see through view of the miniaturized depiction illustrating real time orientation of the 3D model. The container element is user-interactive to effect change in orientation of the 3D model concurrently displayed in a work area of a screen view. The zoom level of the displayed 3D model in the work area remains constant avoiding or omitting zoom to extents throughout user interaction with the GUI widget.

摘要： A computer-implemented method and system automatically solves constraints in a computer-aided design (CAD) model. A CAD model of a real-world object capable of assuming various positions is constructed and a constraint solver process is initiated and executes while a user defines multiple positions of the CAD model. Input of data specified during a CAD design workflow is automatically input to the constraint solver process, and unknown variables are solved for as part of the CAD design workflow.

摘要： A computer-implemented method and system create a three-dimensional (3D) model represented by a sub-division surface and defining a solid or a surface model. A selected entity of the 3D model is selected and with one or more surrounding entities a determination is made of a type of operation to perform. The operation is an add operation or a remove operation, and the operation changes the topology of the 3D model.

摘要： 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 disclosed methods and systems automatically generate dimension and tolerance information for fastened components. Given a source component with dimensions and tolerances, the dimensions and tolerances are automatically applied to mating entities of a target component such that fit is insured without interference when the parts are manufactured at worst case, or at the extremes of their tolerance zones.

摘要： 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.

摘要： In one embodiment, a computer-readable medium is configured to store instructions for creating a model in a three-dimensional (3D) environment, where the model represents a real-world object. The instructions, when loaded and executed by a processor, causes the processor to, given a two-dimensional (2D) sketch comprised of sketch entities, automatically create one or more 3D part in the 3D environment corresponding to respective groupings of sketch entities. 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.

摘要： A computer-implemented method and system creates an interactive learning environment. Windows are created for guiding a user through a series of steps to perform a task supported by a computer software application. The windows contain textual and/or visual content that informs the user of the elements to accomplish the task. At least one of the windows contains a pointer indicating a location of a command in a user interface of the computer software application. User interaction is enabled during the execution of the series of steps, allowing for user input.
