class AngleAspect from Prs3d inherits CompositeAspect from Prs3d
---Purpose: A framework for defining how an angle will be
-- displayed in a presentation. Aspects of angle display include:
-- - display of the arrow pointing to the angle
-- - display of the line making up the shaft of the arrow
-- - display of the text referring to the angle.
-- The definition set by this class is then passed to the
-- attribute manager Prs3d_Drawer.
-- Any object which requires a value for angle aspect as
-- an argument may then be given the attribute manager
-- as a substitute argument in the form of a field such as
-- myDrawer for example.
