摘要： Creating a section view of a computer-aided design model includes creating a cutting line to apply to the computer-aided design model by at least one cut operation, constraining the cutting line by selecting a constraining point on the computer-aided design model or first inferring a geometric candidate to constrain the initial cutting line, and enhancing the cutting line by automatically adding an enhancement according to an enhancement type and adjusting the enhancement via a cursor-controlled device according to a set of rules.

摘要： 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.

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 includes receiving a digital representation of an image and generating CAD sketches from it. The number of surfaces in a CAD model depends upon the number entities at the sketch level. The method keeps the number of created sketch entities and constraints to a minimum. The method includes a scalable approach for a range of images. Each contour is represented by a sequence of points following a path corresponding to a boundary in the image. The method includes classifying each point in a particular one of the contours as a curve region or a corner region contour point, thereby segmenting the contour into plurality of curve regions separated by corner regions. The method includes optimally fitting a curve to each one of the curve regions to create the best possible representation of the curve region. Additionally, the refine algorithm automatically improves the fit wherever needed.

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： A method is disclosed for creating a flattened version of a three-dimensional electrical harness assembly design in a computer-aided design environment. The method includes storing data in computer memory including route segment identifiers, diameters, lengths, and end points for route segments in the electrical harness assembly. A computer processor designates route segments as forming a trunk line of the electrical harness assembly, based on the stored data, and produces a flattened two-dimensional version of the design. All the route segments designated as forming the trunk line are represented in the flattened 2D version by straight connected lines, having a particular orientation (e.g., horizontal), and every other route segment is represented as extending out from the trunk line. The flattened 2D version is displayed on a display screen of a computer.

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： A computer-based method is disclosed for identifying a parting line for molding a real-world part based on computer model of the part. The method includes receiving a computer-based representation of a modeled part and a parting direction for the mold to make a real-world version of the part. Then a computer-based processor characterizes each respective one of a plurality of faces in the computer-based representation of the modeled part as a positive draft face or a negative draft face. The method includes identifying, as at least a segment of the parting line, a boundary edge between a first one of the positive draft faces and a first one of the negative draft faces that neighbors the first one of the positive draft faces.
