Abstract: Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a model including a plurality of geometries, at least one of the geometries being underdefined. The method includes displaying the model and detecting motion using a motion-sensing device. The method includes perturbing at least one of the underdefined geometries in response to the detected motion and according to an unconstrained freedom of that geometry. The method includes displaying the model while perturbing the at least one of the underdefined geometries. The method can be performed by a handheld device.

Abstract: Methods for product data management and corresponding systems and computer-readable mediums. A method includes receiving a three-dimensional CAD model in the data processing system, the CAD model including a plurality of geometries. The method includes receiving at least one system-found equivalence class (EC) including at least one of the geometries, the system-found EC being of a specified EC type, and receiving at least one persistent EC of the specified EC type including at least one of the geometries. The method includes completing any unique persistent member of the persistent EC by finding any other geometries in the CAD model that have an EC relationship with the unique persistent member of the specified EC type. The method includes expanding the user-defined persistent EC by adding any unique found members of the specified EC type to produce a combined EC, and storing and reusing the combined EC.

Abstract: A system and method for fiber-composite part simulation. A method includes receiving a part model in a data processing system, the part model representing a part to be manufactured using a fiber composite material. The method includes defining a spine for the part model and defining a spine-based rosette for the part model. The method includes simulating and displaying the part according to the part model, the fiber composite material, the spine, and the spine-based rosette.
