	Empty constructor
	ShapeAnalysis_FreeBoundsProperties (const TopoDS_Shape &shape, const Standard_Real tolerance, const Standard_Boolean splitclosed=Standard_False, const Standard_Boolean splitopen=Standard_False)
	Creates the object and calls corresponding Init. <shape> should be a compound of faces.
	ShapeAnalysis_FreeBoundsProperties (const TopoDS_Shape &shape, const Standard_Boolean splitclosed=Standard_False, const Standard_Boolean splitopen=Standard_False)
	Creates the object and calls corresponding Init. <shape> should be a compound of shells.
void	Init (const TopoDS_Shape &shape, const Standard_Real tolerance, const Standard_Boolean splitclosed=Standard_False, const Standard_Boolean splitopen=Standard_False)
	Initializes the object with given parameters. <shape> should be a compound of faces.
void	Init (const TopoDS_Shape &shape, const Standard_Boolean splitclosed=Standard_False, const Standard_Boolean splitopen=Standard_False)
	Initializes the object with given parameters. <shape> should be a compound of shells.
Standard_Boolean	Perform ()
	Builds and analyzes free bounds of the shape. First calls ShapeAnalysis_FreeBounds for building free bounds. Then on each free bound computes its properties:
Standard_Boolean	IsLoaded () const
	Returns True if shape is loaded
TopoDS_Shape	Shape () const
	Returns shape
Standard_Real	Tolerance () const
	Returns tolerance
Standard_Integer	NbFreeBounds () const
	Returns number of free bounds
Standard_Integer	NbClosedFreeBounds () const
	Returns number of closed free bounds
Standard_Integer	NbOpenFreeBounds () const
	Returns number of open free bounds
Handle_ShapeAnalysis_HSequenceOfFreeBounds	ClosedFreeBounds () const
	Returns all closed free bounds
Handle_ShapeAnalysis_HSequenceOfFreeBounds	OpenFreeBounds () const
	Returns all open free bounds
Handle_ShapeAnalysis_FreeBoundData	ClosedFreeBound (const Standard_Integer index) const
	Returns properties of closed free bound specified by its rank number
Handle_ShapeAnalysis_FreeBoundData	OpenFreeBound (const Standard_Integer index) const
	Returns properties of open free bound specified by its rank number
Standard_Boolean	DispatchBounds ()
Standard_Boolean	CheckContours (const Standard_Real prec=0.0)
Standard_Boolean	CheckNotches (const Standard_Real prec=0.0)
Standard_Boolean	CheckNotches (Handle< ShapeAnalysis_FreeBoundData > &fbData, const Standard_Real prec=0.0)
Standard_Boolean	CheckNotches (const TopoDS_Wire &freebound, const Standard_Integer num, TopoDS_Wire &notch, Standard_Real &distMax, const Standard_Real prec=0.0)

Detailed Description

     - calculates area of the contour, <br>
     - calculates perimeter of the contour, <br>
     - calculates ratio of average length to average width of the <br>
       contour, <br>
     - estimates average width of contour, <br>
     - finds the notches (narrow 'V'-like sub-contour) on the <br>
       contour. <br>

For getting free bounds this class uses
ShapeAnalysis_FreeBounds class.

For description of parameters used for initializing this
class refer to CDL of ShapeAnalysis_FreeBounds.

Properties of each contour are stored in the data structure
ShapeAnalysis_FreeBoundData.
