class Shell from ShapeAnalysis
|
|
|
|
---Purpose: This class provides operators to analyze edges orientation
|
|
-- in the shell.
|
|
|
|
uses
|
|
Shape from TopoDS,
|
|
Compound from TopoDS,
|
|
IndexedMapOfShape from TopTools

is
|
|
|
|
Clear (me : in out);
|
|
---Purpose: Clears data about loaded shells and performed checks
|
|
|
|
LoadShells (me : in out; shape : Shape from TopoDS);
|
|
---Purpose: Adds shells contained in the <shape> to the list of loaded shells
|
|
|
|
CheckOrientedShells (me : in out; shape : Shape from TopoDS;
|
|
alsofree: Boolean = Standard_False;
|
|
checkinternaledges: Boolean = Standard_False)
|
|
returns Boolean;
|
|
---Purpose: 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
|
|
|
|
IsLoaded (me; shape : Shape from TopoDS) returns Boolean;
|
|
---Purpose: Tells if a shape is loaded (only shells are checked)
|
|
|
|
NbLoaded (me) returns Integer;
|
|
---Purpose: Returns the actual number of loaded shapes (i.e. shells)
|
|
|
|
Loaded (me; num : Integer) returns Shape from TopoDS;
|
|
---Purpose: Returns a loaded shape specified by its rank number.
|
|
-- Returns null shape if <num> is out of range
|
|
|
|
HasBadEdges (me) returns Boolean;
|
|
---Purpose: Tells if at least one edge is recorded as bad
|
|
|
|
BadEdges (me) returns Compound from TopoDS;
|
|
---Purpose: Returns the list of bad edges as a Compound
|
|
-- It is empty (not null) if no edge are recorded as bad
|
|
|
|
HasFreeEdges (me) returns Boolean;
|
|
---Purpose: Tells if at least one edge is recorded as free (not connected)
|
|
|
|
FreeEdges (me) returns Compound from TopoDS;
|
|
---Purpose: Returns the list of free (not connected) edges as a Compound
|
|
-- It is empty (not null) if no edge are recorded as free
|
|
|
|
HasConnectedEdges (me) returns Boolean;
|
|
---Purpose: Tells if at least one edge is connected (shared twice or more)
