package Select3D 

	---Purpose: The Select3D package provides the following services
    	-- -   definition of standard   3D sensitive primitives such as points, curves and faces.
    	-- -   recovery of the bounding boxes in the 2D graphic selection space, if required.
    	-- -   a 3D-2D projector.

    	---Purpose: Provides values for type of sensitivity in 3D.
    	-- These are used to specify whether it is the interior,
    	-- the boundary, or the exterior of a 3D sensitive entity which is sensitive.
