| void | Clear () |
| Clears data about loaded shells and performed checks. More... | |
| void | LoadShells (const TopoDS_Shape &shape) |
| Adds shells contained in the <shape> to the list of loaded shells. More... | |
| 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. More... | |
| Standard_Boolean | IsLoaded (const TopoDS_Shape &shape) const |
| Tells if a shape is loaded (only shells are checked) More... | |
| Standard_Integer | NbLoaded () const |
| Returns the actual number of loaded shapes (i.e. shells) More... | |
| 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. More... | |
| Standard_Boolean | HasBadEdges () const |
| Tells if at least one edge is recorded as bad. More... | |
| 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. More... | |
| Standard_Boolean | HasFreeEdges () const |
| Tells if at least one edge is recorded as free (not connected) More... | |
| 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. More... | |

| 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.

| const Standard_Boolean | alsofree = 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
| void ShapeAnalysis_Shell::Clear | ( | ) |
Clears data about loaded shells and performed checks.
| 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.
| Standard_Boolean ShapeAnalysis_Shell::HasBadEdges | ( | ) | const |
Tells if at least one edge is recorded as bad.
| Standard_Boolean ShapeAnalysis_Shell::HasConnectedEdges | ( | ) | const |
Tells if at least one edge is connected (shared twice or more)
| Standard_Boolean ShapeAnalysis_Shell::HasFreeEdges | ( | ) | const |
Tells if at least one edge is recorded as free (not connected)
| Standard_Boolean ShapeAnalysis_Shell::IsLoaded | ( | const TopoDS_Shape & | shape | ) | const |
Tells if a shape is loaded (only shells are checked)
| 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.
| void ShapeAnalysis_Shell::LoadShells | ( | const TopoDS_Shape & | shape | ) |
Adds shells contained in the <shape> to the list of loaded shells.
| Standard_Integer ShapeAnalysis_Shell::NbLoaded | ( | ) | const |
Returns the actual number of loaded shapes (i.e. shells)
