AIS_DiameterDimension Class Reference

A framework to display diameter dimensions.
A diameter is displayed with arrows and text. The
text gives the length of the diameter.
The algorithm takes a length along a face and
analyzes it as an arc. It then reconstructs the circle
corresponding to the arc and calculates the
diameter of this circle. This diameter serves as a
relational reference in 3d presentations of the surface.

 AIS_DiameterDimension (const TopoDS_Shape &aShape, const Standard_Real aVal, const TCollection_ExtendedString &aText)
 Constructs a diameter display object defined by the
shape aFShape, the dimension aVal and the text aText.

 AIS_DiameterDimension (const TopoDS_Shape &aShape, const Standard_Real aVal, const TCollection_ExtendedString &aText, const gp_Pnt &aPosition, const DsgPrs_ArrowSide aSymbolPrs, const Standard_Boolean aDiamSymbol, const Standard_Real anArrowSize=0.0)
 Constructs a diameter display object defined by the
shape aFShape, the dimension aVal and the text
aText, the point of origin of the diameter aPosition,
and the type of arrow aSymbolPrs with the size anArrowSize.
If the Boolean aDiamSymbol is true.

virtual AIS_KindOfDimension KindOfDimension () const
 Indicates that we are concerned with a length.

virtual Standard_Boolean IsMovable () const
 Returns true if the diameter dimension is movable

Standard_Boolean DiamSymbol ()
 Returns the symbol for diameter dimension. This will
be either arrow, text, or a combination of both.

void SetDiamSymbol (const Standard_Boolean aDiamSymbol)
 Sets the symbol for diameter dimension aDiamSymbol.
This can be an arrow, a text or both.

virtual 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 !!!
