This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for the description of the visual presentation of geometric shape. Only basic presentation attributes, such as colour or linefont, can be associated with points, curves, surfaces, and topological constructs. Advanced visualization functionality such as light sources and surface reflectance are not included. The description of annotation is not included.

The following are within the scope of this part of ISO 10303:

• the visual presentation of mechanical design shape representations;
• the assignment of visual presentation attributes to geometric and topological items;
• algorithms for the projection of 3D shapes into planes;
• the location of shape projections within a window;
• multiple views within one window;
• the background colour of a window;
• point and curve colour;
• point font;
• curve font;
• curve styles dependent on the role of the curves in the definition of a surface;

EXAMPLE Boundary curves and grid curves play different roles in the definition of a surface.

• pre-defined colours;
• pre-defined curve styles.

The following are outside the scope of this part of ISO 10303:

• the presentation of annotation, i.e., text and symbols;
• the assignment of geometric items to layers;
• surface characteristics such as transparency and reflectance;
• multiple windows;
• representation of products;
• hidden line and hidden surface removal;
• surface colour;
• light sources.
