This part, of ISO 10303 specifies the integrated resources necessary for the scope and information requirements for the exchange between application systems of configuration-controlled 3D designs of mechanical parts and assemblies. Configuration in this context only includes data and processes that control the 3D product design data. Exchange is used as a scoping consideration to narrow the scope to only those data which are exchanged as part of the 3D product definition. Organizations exchanging data within the scope of this part of ISO 10303 may have a contractual relationship, the details of which are outside the scope of this part.NOTE - The application activity model in annex E provides a graphical representation of the processes and information flows which are the basis for the definition of the scope of this part of ISO 10303.The following are within the scope of this part of ISO 10303:a) Products that are mechanical parts and assemblies;b) Product, definition data and configuration control data pertaining to the design phase of a product's development;c) The change of a design and data related to the documentation of the change process;d) Five types of shape representations of a part that include wireframe and surface without topology, wireframe geometry with topology, manifold surfaces with topology, faceted boundary representation, and boundary representation;e) Alternate representations of the data by different disciplines during the design phase of a product's life cycle;f) Identification of government, industry, company or other specifications for design, process, surface finish, and materials which are specified by a designer as being applicable to the design of the product;g) The identification of government, industry, company, or other standard parts for the purpose of their inclusion in a product's design;h) Data that are necessary for the tracking of a design's release;i) Data that are necessary to track the approval of a design, a design aspect, or a configuration control aspect of a product;j) Data that identify the supplier of either the product or the design and, where required by an organization, qualification information for the supplier;k) If a part is being designed under a contract, the identification of, and reference to, that contract under which a design is developed;l) The identification of the security classification of a single part or a part when it is a component in an assembly;m) Data that is used in, or results from, the analysis or test of a design which is used as evidence for consideration of a change to a design.The following are outside the scope of part of ISO 10303:a) Data that is used in, or results from, the analysis or test of a design that is not used as evidence for consideration of a change to a design;b) Data that results in changes to the design during the initial design evolution prior to its release;c) Product definition data and configuration control data pertaining to any life cycle phase of a product's development other than design;d) The business data for the management of a design project;e) Alternate representations of the data by different disciplines outside of the design phase (e.g., manufacturing);f) The use of constructive solid geometry for the representation of objects;g) Data that pertains to the visual presentation of any of the shape or configuration control data.
