Detailed Description

This class provides operators to analyze edges orientation in the shell.

Constructor & Destructor Documentation

ShapeAnalysis_Shell()

ShapeAnalysis_Shell::ShapeAnalysis_Shell

(

)

Empty constructor.

Member Function Documentation

BadEdges()

TopoDS_Compound ShapeAnalysis_Shell::BadEdges

(

)

const

Returns the list of bad edges as a Compound It is empty (not null) if no edge are recorded as bad.

CheckOrientedShells()

Standard_Boolean ShapeAnalysis_Shell::CheckOrientedShells	(	const TopoDS_Shape &	shape,
		const Standard_Boolean	alsofree = Standard_False,
		const Standard_Boolean	checkinternaledges = Standard_False
	)

Checks if shells fulfill orientation condition, i.e. if each edge is, either present once (free edge) or twice (connected edge) but with different orientations (FORWARD/REVERSED) Edges which do not fulfill these conditions are bad.

If <alsofree> is True free edges are considered. Free edges can be queried but are not bad

Clear()

void ShapeAnalysis_Shell::Clear

(

)

Clears data about loaded shells and performed checks.

FreeEdges()

TopoDS_Compound ShapeAnalysis_Shell::FreeEdges

(

)

const

Returns the list of free (not connected) edges as a Compound It is empty (not null) if no edge are recorded as free.

HasBadEdges()

Standard_Boolean ShapeAnalysis_Shell::HasBadEdges

(

)

const

Tells if at least one edge is recorded as bad.

HasConnectedEdges()

Standard_Boolean ShapeAnalysis_Shell::HasConnectedEdges

(

)

const

Tells if at least one edge is connected (shared twice or more)

HasFreeEdges()

Standard_Boolean ShapeAnalysis_Shell::HasFreeEdges

(

)

const

Tells if at least one edge is recorded as free (not connected)

IsLoaded()

Standard_Boolean ShapeAnalysis_Shell::IsLoaded

(

const TopoDS_Shape &

shape

)

const

Tells if a shape is loaded (only shells are checked)

Loaded()

TopoDS_Shape ShapeAnalysis_Shell::Loaded

(

const Standard_Integer

num

)

const

Returns a loaded shape specified by its rank number. Returns null shape if <num> is out of range.

LoadShells()

void ShapeAnalysis_Shell::LoadShells

(

const TopoDS_Shape &

shape

)

Adds shells contained in the <shape> to the list of loaded shells.

NbLoaded()

Standard_Integer ShapeAnalysis_Shell::NbLoaded

(

)

const

Returns the actual number of loaded shapes (i.e. shells)
