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

Public Member Functions | |
void | Clear () |
Clears data about loaded shells and performed checks | |
void | LoadShells (const TopoDS_Shape &shape) |
Adds shells contained in the <shape> to the list of loaded shells | |
Standard_Boolean | 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 | |
Standard_Boolean | IsLoaded (const TopoDS_Shape &shape) const |
Tells if a shape is loaded (only shells are checked) | |
Standard_Integer | NbLoaded () const |
Returns the actual number of loaded shapes (i.e. shells) | |
TopoDS_Shape | Loaded (const Standard_Integer num) const |
Returns a loaded shape specified by its rank number. Returns null shape if <num> is out of range | |
Standard_Boolean | HasBadEdges () const |
Tells if at least one edge is recorded as bad | |
TopoDS_Compound | BadEdges () const |
Returns the list of bad edges as a Compound It is empty (not null) if no edge are recorded as bad | |
Standard_Boolean | HasFreeEdges () const |
Tells if at least one edge is recorded as free (not connected) | |
TopoDS_Compound | 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 | |
Standard_Boolean | HasConnectedEdges () const |
Tells if at least one edge is connected (shared twice or more) |
