This section is GB/T Part of 50,716,656.

This section identical with the international standard ISO 10303-507:2001 "Industrial automation systems and integration - Product data representation and exchange Part 507. Application interpreted construct. Geometrically bounded surface "(in English), its technical content and structure and ISO 10303-507:2001 holding Unanimously, for ease of use, we made the following editorial changes.

a) by deleting the ISO foreword, index;

b) For each underlined in bold for EXPRESS English language to describe the entity names, attribute names and function names, etc., in order to maintain its English original intent, in this section, uses its English name, only when it is used as the title, we have to increase their name in front of the English Type attribution described.

Introduction

GB/T 16656 is used for computer interpretable product data representation and exchange of technical standards. Its purpose is to provide a product throughout the whole A lifecycle neutral mechanism independent of any particular system described in the product data. Which describes functionality not only for neutral file post Change, but also to achieve and infrastructure sharing product databases and archiving.

GB/T 16656 composed of several parts, each part published separately. All parts are belonging to one of the following series. description methods, collection A resource, Application interpreted construct, application protocols, abstract test suites, implementation and conformance testing. This section is an application interpreted construct series.

Application interpreted construct (AIC) gives a logical combination of interpretation constructed to support the use of product data in multiple application environment related special Setting function. Constructs integrated resources to support the needs of the public to explain the application protocol to share information.

This part bounded surface geometry model geometry describes the provisions Application interpreted construct. It includes the definition of a pure geometric bounded mold Resource type geometry, geometric model bounded by the basic composition and sculptural curves and surfaces.
