Abstract: A method and system for providing three dimensional (3D) work instructions for modification tasks is provided. The method includes, determining if a 3D model exists for at least a part of an assembly; extracting model based data from a product data manager; assembling a component list for a work instruction with 3D source data; determining if recent model based process data is available for use; and creating a work instruction with 3D source data. The system includes a computing system for executing the foregoing steps.

Abstract: A method of simulating the behavior of a user-interactive environment, the method comprising: (a) running a virtual environment (VE) simulation application that (1) graphically depicts a VE, (2) receives input from a user that corresponds to a user interaction with the VE, and (3) provides graphical output to the user that corresponds to a condition of the VE; (b) running a functional simulation application that determines the condition for the VE at least in part based upon the user input; (c) communicating the user input received by the VE simulation application to the functional simulation application via a high level architecture (HLA) protocol; and (d) communicating the condition determined by the functional simulation application to the VE simulation application via the HLA protocol.
