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 resource for the description of advanced visual presentations 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. Basic presentation attributes are included, such as line font and colour, and more advanced functionality, such as light sources and surface reflectance. The latter are used to provide a more realistic presentation of properties. All presentation attributes 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. The representation of annotation, such as text and symbols, is not specified.

Technical modifications to the first edition of this part of ISO 10303 are categorised as follows: changes to the EXPRESS declarations, new EXPRESS declarations, and changes to definitions of EXPRESS entity data types.

The following aic_mechanical_design_shaded_presentation EXPRESS declarations and interface specifications have been modified:
