Introduction

ISO 10303 is an International Standard for the computer-interpretable representation of product information and for the exchange of product data. The objective is to provide a neutral mechanism capable of describing products throughout their life cycle. This mechanism is suitable not only for neutral file exchange, but also as a basis for implementing and sharing product databases, and as a basis for retention and archiving.

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. An interpreted construct is a common interpretation of the integrated resources that supports shared information requirements among application protocols.

This part of ISO 10303 specifies an application interpreted construct for the description of the visual presentation of the shape of mechanical design models. Shape is projected into a plane display area. The projections themselves are not represented, however the shape and corresponding projection algorithms are given. Presentation attributes are included, such as line font and colour, that may be applied to parts or all of wireframe, surface, and solid models. Association of attributes with topological items is included to provide for the styling of high level shape constructs. Advanced visualization capabilities, such as light sources and surface reflectance are not included. The representation of annotation, such as text and symbols, are not specified.
