This document specifies the application module for AP242 managed model based 3D engineering.

The following are within the scope of this document:

  • products of automotive, aerospace and other mechanical manufacturers and of their suppliers, including parts, assemblies of parts, tools, assemblies of tools, and raw materials;
  • engineering and product data for the purpose of long-term archiving and retrieval;
  • product data management
    • breakdown data representing a parent-child structures, such as functional, physical, system or zonal breakdowns. A breakdown is made of breakdown element;
    • product definition data and configuration control data for managing large numbers of variants of products during the design phase;
    • data describing the changes that have occurred during the design phase, including tracking of the versions of a product and of the data related to the documentation of the change process;
    • delta change: data describing the exchange of differences with respect to a set of data previously sent;
    • identification of standard parts, based on international, national, or industrial standards;
    • release and approval data for product data;
    • data that identify the supplier of a product and related contract information;
    • properties of parts or of tools;
    • references to product documentation represented in a format other than those specified by ISO 10303;
    • product manufacturing information, covering the design and manufacturing planning phase;
    • identification of physically realized parts or of tools, including assembly of physically realized products and recording of test results.
  • process planning
    • process plan information describing the relationships between parts and the tools used to manufacture them and to manage the relationships between intermediate stages of part or tool development.
  • mechanical design
    • different types of geometry models, including:
      • 2D- and 3D-wireframe geometry model;
      • geometrically bounded surface geometry model;
      • topologically bounded surface geometry model;
      • faceted-boundary geometry model;
      • boundary geometry model;
      • compound shape geometry model;
      • constructive solid geometry model;
      • parametric and constrained geometry model;
      • 2D-sketch model;
      • 3D tessellated geometry model;
      • 3D scan data;
      • curved triangles.
    • representation of the shape of parts or tools that is a combination of two or more of different types of geometry models;
    • data that pertains to the presentation of the shape of the product;
    • representation of portions of the shape of a part or a tool by manufacturing features;
    • data defining surface conditions;
    • dimensional and geometrical tolerance data;
    • quality criteria and inspection results of given three dimensional product shape data;
    • product documentation as annotated 3D models and as drawings.
  • message
    • data that identify a message and an envelope.
  • interface
    • data representing the interfaces with version management mechanism and the definition of connection with connectors.
  • mating
    • data representing the detailed assembly information on how the involved part occurrences are mated together and which constraints apply.
  • kinematics
    • simulation data for the description of kinematic structures and motion.
  • analysis management
    • data representing an analysis, managed in versions and the link to the result of the analysis.
  • composite design
    • definition of composite structural parts;
    • the association of the constituents of composite and metallic parts with the constituent shape model;
    • the depiction of composite laminate tables describing the material, stacking sequence and ply orientation;
    • constituents of the composite or a portion of the composite with a defined shape;
    • the identification of material specifications from internal and external sources and their properties for a specific operating environment.
  • electrical harness assembly design
    • electrical wire harnesses design;
    • physical electrical harness model for design and construction;
    • electrical connectivity information in multilevel assemblies;
    • wire and cable list data;
    • definition of wire, cable and connector features.
