◆ CommonVertex()

static Standard_Boolean TopExp::CommonVertex	(	const TopoDS_Edge &	E1,
		const TopoDS_Edge &	E2,
		TopoDS_Vertex &	V
	)

static

Finds the vertex <V> common to the two edges <E1,E2>, returns True if this vertex exists.

Warning: <V> has sense only if the value <True> is returned

◆ FirstVertex()

static TopoDS_Vertex TopExp::FirstVertex	(	const TopoDS_Edge &	E,
		const Standard_Boolean	CumOri = `Standard_False`
	)

static

Returns the Vertex of orientation FORWARD in E. If there is none returns a Null Shape. CumOri = True : taking account the edge orientation.

◆ LastVertex()

static TopoDS_Vertex TopExp::LastVertex	(	const TopoDS_Edge &	E,
		const Standard_Boolean	CumOri = `Standard_False`
	)

static

Returns the Vertex of orientation REVERSED in E. If there is none returns a Null Shape. CumOri = True : taking account the edge orientation.

		TopTools_IndexedMapOfShape &	M
	)

static

Tool to explore a topological data structure. Stores in the map <M> all the sub-shapes of <S> of type <T>.

		const TopAbs_ShapeEnum	TS,
		const TopAbs_ShapeEnum	TA,
		TopTools_IndexedDataMapOfShapeListOfShape &	M
	)

static

Stores in the map <M> all the subshape of <S> of type <TS> for each one append to the list all the ancestors of type <TA>. For example map all the edges and bind the list of faces. Warning: The map is not cleared at first.

◆ MapShapesAndUniqueAncestors()

static void TopExp::MapShapesAndUniqueAncestors	(	const TopoDS_Shape &	S,
		const TopAbs_ShapeEnum	TS,

		const Standard_Boolean	useOrientation = `Standard_False`
	)

static

Stores in the map <M> all the subshape of <S> of type <TS> for each one append to the list all unique ancestors of type <TA>. For example map all the edges and bind the list of faces. useOrientation = True : taking account the ancestor orientation Warning: The map is not cleared at first.

◆ Vertices() [1/2]

static void TopExp::Vertices	(	const TopoDS_Edge &	E,

		TopoDS_Vertex &	Vlast,
		const Standard_Boolean	CumOri = `Standard_False`
	)

static

Returns in Vfirst, Vlast the FORWARD and REVERSED vertices of the edge <E>. May be null shapes. CumOri = True : taking account the edge orientation.

		TopoDS_Vertex &	Vfirst,
		TopoDS_Vertex &	Vlast
	)

static

Returns in Vfirst, Vlast the first and last vertices of the open wire <W>. May be null shapes. if <W> is closed Vfirst and Vlast are a same vertex on <W>. if <W> is no manifold. VFirst and VLast are null shapes.
