Introduction

GB/T 16656 is a computer-interpretable representation and exchange of product data standards, the goal is to provide products throughout the entire life , Neutral mechanism independent of any particular system described product data cycle. The nature of this description makes it suitable not only neutral file Exchange, but also to achieve shared infrastructure and product database and file archives.

GB/T 16656 by a series of parts, each part published separately. GB/T 16656 all parts are belong to the following series A. Describe the method, resource integration, application interpreted construct, application protocols, abstract test suites, implementation and conformance testing and application modules.

This section is an application interpreted construct series.

Application interpreted construct (AIC) provides a logical combination of tectonic interpretation of these explanations configuration across multiple application environments to support the number of products According to a specific function uses. It constructs a general explanation of integrated resources that support different application protocols shared information needs.

This part of non-manifold geometric surface model for the description of the appearance of the provisions Application interpreted construct. It includes the geometry and topology of resources, with in the definition of non-manifold surfaces from the base curves and surfaces as well as sculptures composed of curves and surfaces.

GB/T 16656.508-2010/ISO 10303-508:2001 Industrial automation systems and integration - Product data representation and Exchange - Part 508. Application interpreted construct.
