package BRepBuilderAPI 

	---Purpose: The  BRepBuilderAPI  package   provides  an   Application
	--          Programming Interface  for the BRep  topology data
	--          structure.
	--          
	--          The API is a set of classes aiming to provide :
	--          
	--          * High level and simple calls  for the most common
	--          operations. 
	--          
	--          *    Keeping   an   access  on    the    low-level
	--          implementation of high-level calls.
	--          
	--          * Examples  of programming of high-level operations
	--          from low-level operations.
	--          
	--          * A complete coverage of modelling :
	--          
	--             - Creating vertices ,edges, faces, solids.
	--             
	--             - Sweeping operations.
	--             
	--             - Boolean operations.
	--             
	--             - Global properties computation.
	--
	-- 	    
	-- 	    The API provides  classes to  build  objects:
	-- 	    
	-- 	    * The  constructors  of the classes  provides  the
	-- 	    different constructions methods.
	-- 	    
	-- 	    * The  class keeps as fields the   different tools
	-- 	    used to build the object.
	-- 	    
	-- 	    *   The class  provides  a  casting  method to get
	-- 	    automatically the  result  with  a   function-like
	-- 	    call. 
	-- 	    
	-- 	    For example to make a  vertex <V> from a point <P>
	-- 	    one can writes :
	-- 	    
	-- 	    V = BRepBuilderAPI_MakeVertex(P);
	-- 	    
	-- 	    or
	-- 	    
	-- 	    BRepBuilderAPI_MakeVertex MV(P);
	-- 	    V = MV.Vertex();
	-- 	    
	-- 	    
	-- 	    For tolerances  a default precision is  used which
	-- 	    can    be   changed    by    the   packahe  method
	-- 	    BRepBuilderAPI::Precision. 
	-- 	    
	-- 	    For error handling the BRepBuilderAPI commands raise only
	-- 	    the NotDone error. When Done is false on a command
	-- 	    the error description can be asked to the command.
	-- 	    
	-- 	    In  theory  the  comands can be    called with any
	-- 	    arguments, argument  checking  is performed by the
	-- 	    command.

	-- construction of an edge, i.e. whether it has been successful or
	-- not, as explained below:

	--    correctly built.
	-- -      BRepBuilderAPI_PointProjectionFailed No parameters were given but
	--    the projection of the 3D points on the curve failed. This
	--    happens when the point distance to the curve is greater than
	--    the precision value.
	-- -      BRepBuilderAPI_ParameterOutOfRange
	--    The given parameters are not in the parametric range
	--   C->FirstParameter(), C->LastParameter()
	-- -      BRepBuilderAPI_DifferentPointsOnClosedCurve
	--    The two vertices or points are the extremities of a closed
	--    curve but have different locations.
	-- -      BRepBuilderAPI_PointWithInfiniteParameter
	--    A finite coordinate point was associated with an infinite
	--    parameter (see the Precision package for a definition of    infinite values).
	-- -      BRepBuilderAPI_DifferentsPointAndParameter
 	--   The distance between the 3D point and the point evaluated
	--    on the curve with the parameter is greater than the precision.
	-- -      BRepBuilderAPI_LineThroughIdenticPoints
	--    Two identical points were given to define a line (construction
	--    of an edge without curve); gp::Resolution is used for the    confusion test.

	-- -      BRepBuilderAPI_EmptyWire No
	-- initialization of the algorithm. Only an empty constructor was used.
	-- -      BRepBuilderAPI_DisconnectedWire
	-- The last edge which you attempted to add was not connected to the wire.

	--    correctly built.
	-- -      BRepBuilderAPI_NoFace No initialization of the
	--    algorithm; only an empty constructor was used.

	-- to determine what has happened to the shapes which
	-- constitute the list of operands.
