ISO 10303-242 specifies the application protocol for Managed model based 3d engineering.

The following are within the scope of ISO 10303-242:

• 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;

    • 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;
