class MakeHalfSpace from BRepPrimAPI  inherits MakeShape from BRepBuilderAPI

	---Purpose: Describes functions to build half-spaces.
    	-- A half-space is an infinite solid, limited by a surface. It
    	-- is built from a face or a shell, which bounds it, and with
    	-- a reference point, which specifies the side of the
    	-- surface where the matter of the half-space is located.
    	-- A half-space is a tool commonly used in topological
    	-- operations to cut another shape.
    	-- A MakeHalfSpace object provides a framework for:
    	-- -   defining and implementing the construction of a half-space, and
    	-- -   consulting the result.
