Abstract: A computer-aided design system and computer-implemented method define initial conditions for dynamic simulation of an assembly of objects in a three-dimensional scene of a computer-aided design. The system and method provide (S1) the assembly of objects with information relative to kinematic joints linking objects of the assembly. The system/method provide (S2) a manipulating tool (M) embedded in the scene; attach (S3) said manipulating tool (M) to one object of the assembly; select (S4) a degree of freedom of the manipulating tool (M) attached to the object of the assembly; and input (S5) at least one initial condition (IC) according to said selected degree of freedom, an initial condition comprising an initial position and/or an initial speed and/or an initial acceleration. The tool has a referential (reference) with three-axes allowing for each axis a degree of freedom in translation and a degree of freedom in rotation. Next the system and method calculate (S6) and display in real time the dynamic simulation taking into account the initial conditions (IC) previously defined.

Abstract: A computer-implemented method and system enables visualization of a computer-generated annotation on a real-world object in a real-world environment on a computerized system. The method and system creates a three-dimensional (3D) model of the real-world object, simultaneously displays the 3D model, the real-world object, and the real-world environment on a computer screen, and aligns the displayed 3D model and the displayed real-world object. The visibility of the 3D model is reduced and the 3D model is annotated in a real-world context. Reducing the visibility of the 3D model causes the annotation to appear on the displayed real-world object.

Abstract: The invention notably relates to a computer-implemented method for designing a 3D modeled object representing a real object. The method comprises the steps of providing a 3D representation of the real object, identifying occurrences of a geometric feature at 3D positions of the 3D representation, providing at least one 2D view of the real object, identifying occurrences of a graphic feature at 2D positions of the 2D view, the geometric feature corresponding to the graphic feature, computing camera parameters that minimize a distance between a set of projections of the 3D positions on the 2D view and a set of 2D positions. This provides an improved solution for designing a 3D modeled object representing a real object.

Abstract: A process updates a status of relation between objects in a system of computer-aided design, for subsequent analysis of status of relation. The process identifies a set of data of a group of objects, preferably a pair of objects; a method of computation of relations between objects; and an expected relation of executing the method identified using the set. Next the process executes the method using the set of data to compute a relation. A comparison step compares the expected relation with the computed relation. The process updates a status of the expected relation based on a result of the comparing step.

Abstract: A method and apparatus for manipulating a computer generated model and visualizing a change in projection plane before entering a projection creation command. After selection of a projection plane on the 3-D model, a generative drafting document can be created wherein the projection plane becomes the plane of the screen. The system can display a visualization of the projection of the model in plane with the screen, without generating a fully computed projection. Display of the visualization can provide increased efficiency in processing time as compared to a fully computed projection. The system can also display a graphical manipulator including a circular central region with a button in the middle, wherein clicking on the button can be used as a command to the system requesting creation of the projection. The graphical manipulator software tool can also include quadrants, wherein each quadrant is associated with a direction in relation to an orthogonal axis. The four quadrants can be defined as left, right, up and down: Clicking on a quadrant can cause the projection plane to rotate by 90 degrees, or other predetermined amount, around two orthogonal axes of the model in the projection plane. The direction of rotation will correlate with the quadrant selected. In addition, the manipulator tool can include a pin tracking the circumference of a circle displayed on a computer screen. Selection of the pin and rotation can cause the projection plane of a computer generated model to rotate about an axis which is perpendicular to the projection screen.

The logical component hierarchy includes an ancestor component and a descendant component associated with the ancestor component. The method uses a computer device in communication with a memory. The method includes determining, by the computer device, a requirement to replace the descendant component, within the logical component hierarchy, with an overriding component. The overriding component is associated with the ancestor component by an overriding reference.

Abstract: A computer-implemented method for use in analyzing a model of a repetitive structure includes generating a plurality of blocks based on the model such that the blocks are arranged end to end. The method also includes defining at least one boundary condition on an inlet of the model and on an outlet of the model, generating a plurality of constraints to be applied to the blocks to define connectivity between adjacent blocks, defining an inlet state based on the boundary condition and at least a portion of the constraints. The method further includes detecting when a first block passes a trigger plane at the inlet of the model, erasing a state of a second block at the outlet of the model, shuffling the second block to an inlet zone, and resetting the state of the second block to the inlet state.
