13、International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee

14、 has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnic

15、al standardization. Draft International Standards adopted by technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10303-515 was prepared by Tech

16、nical Committee ISO/TC 184, Industrial automation systems and integration, Subcommittee SC4, Industrial data. This International Standard is organized as a series of parts, each published separately. The parts of ISO 10303 fall into one of the following series: description methods, integrated resour

17、ces, application protocols, abstract test suites, implementation methods, and conformance testing. The series are described in ISO 10303-1. A complete list of parts of ISO 10303 is available from the internet: http:/www.nist.gov/sc4/editing/step/titles/ Annexes A and B form a normative part of this

18、part of ISO 10303. Annexes C and D are for information only. ISO ISO 10303-515:2000(E)vi Introduction ISO 10303 is an International Standard for the computer-interpretable representation and exchange of product data. The objective is to provide a neutral mechanism capable of describing product data

19、throughout the life cycle of a product, independent from any particular system. The nature of this description makes it suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases and archiving. This International Standard is organized as a series

20、of parts, each published separately. The parts of ISO 10303 fall into one of the following series: description methods, integrated resources, application interpreted constructs, application protocols, abstract test suites, implementation methods, and conformance testing. The series are described in

21、ISO 10303-1. This part of ISO 10303 is a member of the application interpreted constructs series. An application interpreted construct (AIC) provides a logical grouping of interpreted constructs that supports a specific functionality for the usage of product data across multiple application contexts

22、. An interpreted construct is a common interpretation of the integrated resources that supports shared information requirements among application protocols. This document specifies the application interpreted construct for a consistent set of geometric and structural entities for the definition of C

23、onstructive Solid Geometry (CSG). The geometric information is conveyed by solid models, and the structural information is communicated through acyclic graphs.

24、sentation and exchange Part 515: Application interpreted construct: Constructive solid geometry 1S c o p e This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for representation of product shape using constructive solid geometry. The following are

25、within the scope of this part of ISO 10303: solid primitives; EXAMPLE 1 - sphere, right circular cone, right circular cylinder, and torus are types of solid primitives. regularised boolean operations of union, intersection, and difference on solid primitives, manifold brep and other solids; EXAMPLE

26、2 - manifold solid breps, extruded face solids, revolved face solids, solid replicas, and half- space solids are other types of solids. extruded_face_solids and swept_face_solids to define new primitive shapes; boolean results generated by applying operators to solids. The following are outside the

27、scope of this part of ISO 10303: 2D geometric entities; self-intersecting geometry; evaluation of constructive solid geometry models to generate B-rep models.ISO 10303-515:2000(E) ISO 2 2 Normative references The following normative documents contain provisions which, through reference in this text,

39、 NOTE 1 - There may be subtypes and items of select lists that appear in the integrated resources that are not imported into the AIC. Constructs are eliminated from the subtype tree or select list through the use of the implicit interface rules of ISO 10303-11. References to eliminated constructs ar

40、e outside the scope of the AIC. In some cases, all items of the select list are eliminated. Because AICs are intended to be implemented in the context of an application protocol, the items of the select list will be defined by the scope of the application protocol.
