deferred  class Builder from BOP 

	---Purpose:  
	
        --  The Root class to perform a Boolean Operations (BO)

uses 

    Shape from TopoDS, 
    Operation from BOP, 
    HistoryCollector from BOP,
    ShapeEnum from TopAbs, 
    DSFiller  from BOPTools,
    PDSFiller from BOPTools, 
     
    IndexedDataMapOfShapeListOfShape from TopTools, 
    ListOfShape       from TopTools, 
    IndexedMapOfShape from TopTools

    ---Purpose:  
    --  Set shapes (arguments) to perform BO        
    ---
    SetOperation    (me:out;

    ---Purpose:  
    --  Set type of the BO to perform    	     
    -- 
    SetManifoldFlag (me:out;

    ---Purpose:   
    --           Does the BO from the beggining to the end, 
    --           i.e.  create new DataStructure, DSFiller,

    --  Sort types of shapes as integers in increasing order
