-- <adn@houblon>

class Axis from AIS inherits InteractiveObject from AIS
---Purpose: Locates the x, y and z axes in an Interactive Object.
-- These are used to orient it correctly in presentations
-- from different viewpoints, or to construct a revolved
-- shape, for example, from one of the axes. Conversely,
-- an axis can be created to build a revolved shape and
-- then situated relative to one of the axes of the view.
