Attribute Management

The Attribute Management tool-kit provides services for advanced programmers to extend the Application Interactive Services component, AIS. This would prove necessary in situations where new Interactive Objects were required.

The Prs3d package provides the following services:

- a presentation object (the context for all modifications to the display, its presentation will be displayed in every view of an active viewer)

- an attribute manager governing how objects such as color, width, and type of line are displayed; these are generic objects, whereas those in StdPrs are specific geometries and topologies.

- generic algorithms providing default settings for objects such as points, curves, surfaces and shapes

- a root object which provides the abstract framework for the DsgPrs definitions at work in display of dimensions, relations and trihedrons.
