15、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 has been established has the right to be represented on that committee. International organizat
16、ions, 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 electrotechnical standardization. International Standards are drafted in accordance with the rules given in th
17、e ISO/IEC Directives, Part 3. Draft International Standards adopted by the 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. Attention is drawn to the possibility that
18、some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 10303-507 was prepared by Technical Committee ISO/TC 184 Industrial automation systems and integration,
19、 Subcommittee SC 4, Industrial data. This International Standard is organized as a series of parts, each published separately. The structure of this International Standard is described in ISO 10303-1. Each part of this International Standard is a member of one of the following series: description me
20、thods, implementation methods, conformance testing methodology and framework, integrated generic resources, integrated application resources, application protocols, abstract test suites, application interpreted constructs, and application modules. This part is a member of the application interpreted
21、 construct series. A complete list of parts of ISO 10303 is available from the Internet:Annexes A and B form a normative part of this part of ISO 10303. Annexes C and D are for information only.ISO 10303-507:2001(E) vi ISO 2001 All rights reserved Introduction ISO 10303 is an International Standard
22、for the computerinterpretable representation and exchange of product data. The objective is to provide a neutral mechanism capable of describing product data throughout the life cycle of a product independent from any particular system. The nature of this de scription makes it suitable not only for
23、neutral le exchange, but also as a basis for implementing and sharing product databases and archiving. 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 resources, ap
24、plication interpreted constructs, application protocols, abstract test suites, implementation methods, and confor mance testing. The series are described in ISO 103031. This part of ISO 10303 is a member of the application interpreted constructs series. An application interpreted construct (AIC) pro
25、vides a logical grouping of interpreted constructs that supports a specic functionality for the usage of product data across multiple application contexts. An interpreted construct is a common interpretation of the integrated resources that supports shared infor mation requirements among application
26、 protocols. This document species the application interpreted construct for the description of geometric shapes by means of geometrically bounded surface models. It includes the geometric resources to dene purely geometrically bounded models that consist of elementary and sculptured curves and surfa
27、ces.INTERNATIONAL STANDARD ISO 10303-507:2001(E) Industrial automation systems and integration Product data representation and exchange Part 507: Application interpreted construct: Geometrically bounded surface 1S c o p e This part of ISO 10303 species the interpretation of the integrated resources
28、in order to satisfy require ments for the representation of geometric shapes by means of geometrically bounded surface models.

NOTE 1 There may be subtypes and items of select lists that appea
44、r 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 4c ISO2001Allrightsreserved ISO10303507:200 1(E)the implicit interface rules of ISO 1030311. References to eliminated constructs are outside the scope o
45、f 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 dened by the scope of the application protocol. This application interpreted construct provides a consist
46、ent set of geometric entities for the denition of surface models that consist of points, elementary or sculptured curves, and elementary or sculptured surfaces. Geometry shall be bounded; no topological entities are used for bounding. EXPRESS specication: *) SCHEMA aic_geometrically_bounded_surface;
