Abstract: A method of cloning models of a physical fastener may include a computer-aided design (CAD) system receiving one or more instructions that identify a base model of a physical fastener. For each of one or more socket models having at least one characteristic corresponding to the base model, the method may further include generating a clone fastener model based on the base model of a physical fastener and at least one physical property of the one or more socket models.

Abstract: A computer-implemented method and system automatically detects stress singularity in a three-dimensional (3D) computer-aided design (CAD) model. A potential area of high stress is detected. A finite element mesh of the 3D CAD model is refined, at least in the potential area of high stress, after which, whether the high stress value converges is determined. A user is alerted that the potential area of high stress is an area having one or more elements of stress singularity. Suggestions are made regarding how to eliminate the stress singularity and the user is enabled to modify the design of the 3D CAD model to eliminate the stress singularity.

Abstract: A method of executing a simulation model while generating an associated structural model includes changing, by a computer-aided design (CAD) system, the structural model. The method further includes evaluating, by the CAD system, at least one trigger criterion to determine if the change to the structural model is a simulation trigger event. The method also includes executing, by the CAD system, the simulation model if the change to the structural model is determined to be the simulation trigger event.

Abstract: A system and method provide access by a web application running on a host computing device in communication with a remote server to a native binary DLL. A browser extension to the web application and a native messaging application communicate with the browser extension via standard input/output. A long-running computational process on the host computing device configured as a wrapper for the binary DLL is executable by the host computing device. The native messaging application and the long-running computational process communicate with one another via a named pipe, and the long-running computational process duration is independent of the native messaging application duration.

Abstract: A computer-implemented method for applying, to a given curve, a CAD deformation operator. The given curve results from a conversion of a corresponding subdivision curve defined by a base mesh into a computer-aided design (CAD) curve format. The CAD deformation operator is configured to deform an input CAD object so as to create a contact geometrical relation with another CAD object. The method comprises converting the given curve into a format readable by the CAD deformation operator. The method further comprises applying the CAD deformation operator to the converted given curve. The method further comprises converting back the result of applying the CAD deformation operator into the CAD curve format.

Abstract: A computer-implemented method for converting a subdivision curve into a corresponding computer-aided design (CAD) curve format. The subdivision curve is controlled by a base mesh. The base mesh is formed by vertices connected by one or more edges. The subdivision curve defines at least a part of a product to be manufactured for designing the product. The method comprises transforming the subdivision curve into a G2-continous CAD curve. The CAD curve is formed by the union of one or more Bezier curves. Each Bezier curve corresponds to a respective edge of the base mesh. A control polygon of the CAD curve is computed from the base mesh. The transformation is based on a Catmull-Clark refinement process.

Abstract: A method for designing a mechanism including rigid bodies and mechanical joints including obtaining input parameter values which represent the mechanism in an input state. The method also includes determining output parameter values which represent the mechanism in an output state. The determining includes minimizing an objective function under constraints. The objective function penalizes a distance between the output dimensional values and the input dimensional values. The constraints include a first constraint representing verification of the closure equation by the output parameter values. The constraints further include a second constraint representing mobility of the mechanism in the output state. This forms an improved solution for designing a mechanism comprising rigid bodies and mechanical joints.

Abstract: A system and method for accessing a remotely located two dimensional (2D) drawing via a mobile device at a work site includes a reference device at the work site configured to provide a geographical reference to the mobile device. A document retrieval system is configured to access the plurality of 2D drawings in a document repository. The mobile device provides an annotated document to the document retrieval system. The document retrieval system accesses the 2D drawing in the document repository based on the annotated document, and provides a rasterized version of the 2D drawing to the mobile device.

Abstract: Embodiments perform automatic slot propagation in CAD models. One such embodiment identifies a first instance of a tab feature in a CAD model. The first instance of the tab feature is associated with a corresponding first instance of a slot feature. Next, a second instance of the tab feature in the CAD model is identified, e.g., a tab that does not have a slot. In turn, the slot feature is automatically propagated by creating a second instance of the slot feature in a component of the CAD model. The second instance of the slot feature corresponds to the identified second instance of the tab feature. In this way, embodiments automatically create slots for tabs without slots.
