class Presentation from Prs3d inherits Structure from Graphic3d
---Purpose: Defines a presentation object which can be displayed,
-- highlighted or erased.
-- The presentation object stores the results of the
-- presentation algorithms as defined in the StdPrs
-- classes and the Prs3d classes inheriting Prs3d_Root.
-- This presentation object is used to give display
-- attributes defined at this level to
-- ApplicationInteractiveServices classes at the level above.
