Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.

Public Member Functions
	BRepBuilderAPI_FastSewing (const double theTolerance=1.0e-06)
	Creates an object with tolerance of connexity.

bool	Add (const TopoDS_Shape &theShape)
	Adds faces of a shape.

bool	Add (const occ::handle< Geom_Surface > &theSurface)
	Adds a surface.

void	Perform ()
	Compute resulted shape.

void	SetTolerance (const double theToler)
	Sets tolerance.

double	GetTolerance () const
	Returns tolerance.

const TopoDS_Shape &	GetResult () const
	Returns resulted shape.

FS_VARStatuses	GetStatuses (Standard_OStream *const theOS=nullptr)
	Returns list of statuses. Print message if theOS != 0.

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()=default
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.

bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

int	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

virtual void	Delete () const
	Memory deallocator for transient classes.

Protected Member Functions
void	FindVertexes (const int theSurfID, NCollection_CellFilter< NodeInspector > &theCells)

void	FindEdges (const int theSurfID)

void	UpdateEdgeInfo (const int theIDPrevVertex, const int theIDCurrVertex, const int theFaceID, const int theIDCurvOnFace)

void	CreateNewEdge (const int theIDPrevVertex, const int theIDCurrVertex, const int theFaceID, const int theIDCurvOnFace)

double	Compute3DRange ()

FS_VARStatuses	SetStatus (FS_Statuses theStatus)
	Sets status. Returns numeric value of the status set.

Additional Inherited Members
Static Public Member Functions inherited from Standard_Transient
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.

static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

It supposes that all surfaces are finite and are naturally restricted by their bounds. Moreover, it supposes that stitched together surfaces have the same parameterization along common boundaries, therefore it does not perform time-consuming check for SameParameter property of edges.

For sewing, use this function as following:

set tolerance value (default tolerance is 1.E-06)
add all necessary surfaces (faces)
check status if adding is correctly completed.
compute -> Perform
retrieve the error status if any
retrieve the resulted shape
