class ProjShape from AIS2D inherits InteractiveObject from AIS2D
---Purpose: Constructs presentable and selectable projection of
-- TopoDS_Shape on the view plane
uses
Shape from TopoDS,
Line from Graphic2d,
ListOfShape from TopTools,
Projector from HLRAlgo,
Algo from HLRBRep,
PolyAlgo from HLRBRep,

SetOfCurves from GGraphic2d
is
Create returns mutable ProjShape from AIS2D;
---Purpose: Initializes the projected shape
Create( aProjector: Projector from HLRAlgo;
nbIsos: Integer from Standard = 3;
isPolyAlgo: Boolean from Standard = Standard_False;
visHL: Boolean from Standard = Standard_True )
returns mutable ProjShape from AIS2D;
---Purpose: Initializes the projected shape with projector <aProjector>, number isolines <nbIsos>
Add( me: mutable; aShape: Shape from TopoDS );
---Level: Public
---Purpose: Adds <aShape> to the list of projected shapes.
SetProjector( me: mutable; aProjector: Projector from HLRAlgo );
---Level: Public
---Purpose: sets the projector <aProjector>
Projector( me ) returns Projector from HLRAlgo;

---Purpose: Indicates the projector
SetNbIsos( me: mutable; aNbIsos: Integer from Standard );
---Level: Internal
---Purpose:
SetPolyAlgo( me: mutable; aIsPoly: Boolean from Standard = Standard_False );
---Level: Internal
---Purpose: sets the projection of the shape as a polyhedral
-- simplification of the shape if <aIsPoly> is True
SetHLMode( me: mutable; aIsHLM: Boolean from Standard = Standard_True );
---Level: Internal
---Purpose: Sets the hidden line mode if <aIsHLM> is True
IsHLMode( me ) returns Boolean from Standard;
---Level: Public
---Purpose: Indicates the hidden lines are visible
GetNbIsos( me ) returns Integer from Standard;
---Level: Public
---Purpose: Indicates the number of isolines
GetIsPoly( me ) returns Boolean from Standard;
---Level: Public
---Purpose: Indicates the shape was extracted as Algo or PolyAlgo
GetPrimitives( me ) returns Line from Graphic2d;
---Level: Internal
---Purpose: Returns the set of primitives are included into Shape,
-- except hidden lines
GetHLPrimitives( me ) returns Line from Graphic2d;
---Level: Internal
---Purpose: Returns the set of hidden line primitives are included into Shape
ShowEdges( me: mutable;
aSharp, aSmooth, aSewn, anOutline, anIsoline: Boolean from Standard = Standard_True );
---Level: Public
---Purpose: Sets the flags for display of all types of edges
