Abstract: Methods and computer systems for methods, computer systems, and computer-readable memory media for constructing a system model. A first computer-aided x (CAx) model of a tangible object is received that is described in a first CAx model domain and includes a first model-based definition (MBD) and first CAx product manufacturing information (PMI). The first MBD includes geometric data and topological data. Second CAx PMI is received from a second CAx model domain different from the first CAx model domain. The second CAx PMI is mapped to the topological data of the first MBD using a systems modelling language, and a system model is constructed that includes the first MBD and the mapped second CAx PMI. The system model is stored in a non-transitory computer-readable memory medium.

Abstract: Methods and computer systems for methods, computer systems, and computer-readable memory media for determining a warp function. A first watertight spline model of a first object and a set of points and associated metadata from a second object are received. A second watertight spline model of the second object is constructed based on the set of points, the metadata, and the first watertight spline model. A warp function is determined based on a difference between the first watertight spline model and the second watertight spline model. The warp function is a continuous function approximating differences between the first object and the second object. The warp function is stored in a non-transitory computer-readable memory medium.

Abstract: Determining a warp function between two watertight spline models. A first watertight spline model of a first object and a set of points and associated metadata from a second object are received. A second watertight spline model of the second object is constructed based on the set of points, the metadata, and the first watertight spline model. A warp function is determined based on a difference between the first watertight spline model and the second watertight spline model. The warp function is a continuous function approximating differences between the first object and the second object. The warp function is stored in a non-transitory computer-readable memory medium.
