◆ 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)
