# AIS_RadiusDimension Class Reference

A framework to define display of radii.
These displays serve as relational references in 3D
presentations of surfaces, and are particularly useful
in viewing fillets. The display consists of arrows and
text giving the length of a radius. This display is
recalculated if the applicative owner shape changes
in dimension, and the text gives the modified length.
The algorithm analyzes a length along a face as an
arc. It then reconstructs the circle corresponding to
the arc and calculates the radius of this circle.

## Public Member Functions

Standard_EXPORT | AIS_RadiusDimension (const TopoDS_Shape &aShape, const Standard_Real aVal, const TCollection_ExtendedString &aText)
| Constructs the radius display object defined by the shape aShape, the dimension aVal, and the text aText. .
Standard_EXPORT | AIS_RadiusDimension (const TopoDS_Shape &aShape, const Standard_Real aVal, const TCollection_ExtendedString &aText, const gp_Pnt &aPosition, const DsgPrs_ArrowSide aSymbolPrs, const Standard_Real anArrowSize=0.0)
| Constructs radius display object defined by the shape aShape, the dimension aVal, the position aPosition, the type of arrow aSymbolPrs, the arrow length anArrowSize and the text aText. .
Standard_EXPORT void | SetFirstShape (const TopoDS_Shape &aFShape)
virtual AIS_KindOfDimension | KindOfDimension () const
| Indicates that the dimension selected is a radius. .
virtual Standard_Boolean | IsMovable () const
| Returns true if the radius selected is movable. .
Standard_Boolean | DrawFromCenter () const
| Draws an arrowhead pointing towards the center of the shape aShape defined at construction time if false, and away from the center if true. .
void | SetDrawFromCenter (const Standard_Boolean drawfromcenter)
| Sets the Boolean drawfromcenter to true or false. If drawfromcenter is false, the arrowhead will point towards the center of the shape aShape defined at construction time. .
virtual Standard_EXPORT void | Compute (const Handle(Prs3d_Projector)&aProjector, const Handle(Geom_Transformation)&aTrsf, const Handle(Prs3d_Presentation)&aPresentation)
| computes the presentation according to a point of view given by <aprojector>. To be Used when the associated degenerated Presentations have been transformed by <atrsf> which is not a Pure Translation. The HLR Prs can't be deducted automatically WARNING :<atrsf> must be applied to the object to display before computation !!!

## Private Member Functions

virtual Standard_EXPORT void | Compute (const Handle(PrsMgr_PresentationManager3d)&aPresentationManager, const Handle(Prs3d_Presentation)&aPresentation, const Standard_Integer aMode=0)
| Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. aPresentableObject has the display mode aMode; this has the default value of 0, that is, the wireframe display mode. .
Standard_EXPORT void | Compute (const Handle(Prs3d_Projector)&aProjector, const Handle(Prs3d_Presentation)&aPresentation)

Calculates the 3D view aPresentation and its
updates. The latter are managed by
aPresentationManager. Each of the views in the
viewer and every modification such as rotation, for
example, entails recalculation.
It must be redefined to implement hidden line removal
for the object. The user never calls this method
himself. This is done via the InteractiveContext object
and is dependent on the point of view from which the
object is displayed.
.

Standard_EXPORT void | Compute (const Handle(PrsMgr_PresentationManager2d)&aPresentationManager, const Handle(Graphic2d_GraphicObject)&aPresentation, const Standard_Integer aMode=0)
| Calculates the 2D view aPresentation and its updates. The latter are managed by aPresentationManager. aPresentableObject has the display mode aMode; this has the default value of 0, that is, the wireframe display mode. Note that this syntax is not used in AIS as that package only concerns 3D display. .
virtual Standard_EXPORT void | ComputeSelection (const Handle(SelectMgr_Selection)&aSelection, const Standard_Integer aMode)

Recovers and calculates any sensitive primitive,
aSelection, available in Shape mode, specified by
aMode. As a rule, these are sensitive faces.
This method is defined as virtual. This enables you to
implement it in the creation of a new class of AIS
Interactive Object. You need to do this and in so
doing, redefine this method, if you create a class
which enriches the list of signatures and types.
