Public Member Functions
	ShapeFix_Shell ()
	Empty constructor.

	ShapeFix_Shell (const TopoDS_Shell &shape)
	Initializes by shell.

void	Init (const TopoDS_Shell &shell)
	Initializes by shell.

bool	Perform (const Message_ProgressRange &theProgress=Message_ProgressRange())
	Iterates on subshapes and performs fixes (for each face calls ShapeFix_Face::Perform and then calls FixFaceOrientation). The passed progress indicator allows user to consult the current progress stage and abort algorithm if needed.

bool	FixFaceOrientation (const TopoDS_Shell &shell, const bool isAccountMultiConex=true, const bool NonManifold=false)
	Fixes orientation of faces in shell. Changes orientation of face in the shell, if it is oriented opposite to neighbouring faces. If it is not possible to orient all faces in the shell (like in case of mebious band), this method orients only subset of faces. Other faces are stored in Error compound. Modes : isAccountMultiConex - mode for account cases of multiconnexity. If this mode is equal to true, separate shells will be created in the cases of multiconnexity. If this mode is equal to false, one shell will be created without account of multiconnexity.By default - true; NonManifold - mode for creation of non-manifold shells. If this mode is equal to true one non-manifold will be created from shell contains multishared edges. Else if this mode is equal to false only manifold shells will be created. By default - false.

	Sends a fail to be attached to the shape. Calls SendMsg with gravity set to Message_Fail.

void	SendFail (const Message_Msg &message) const

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.
