 Select3D_SensitiveCurve (const Handle< SelectBasics_EntityOwner > &OwnerId, const Handle< Geom_Curve > &TheCurve, const Standard_Integer MaxPoints=17)
 Constructs a sensitive curve object defined by the
owner OwnerId, the curve TheCurve, and the
maximum number of points on the curve: MaxPoints.

 Select3D_SensitiveCurve (const Handle< SelectBasics_EntityOwner > &OwnerId, const Handle< TColgp_HArray1OfPnt > &ThePoints)
 Constructs a sensitive curve object defined by the
owner OwnerId and the set of points ThePoints.

 Select3D_SensitiveCurve (const Handle< SelectBasics_EntityOwner > &OwnerId, const TColgp_Array1OfPnt &ThePoints)
 Creation of Sensitive Curve from Points.
Warning : This Method should disappear in the next version...

Standard_Boolean Matches (const Standard_Real X, const Standard_Real Y, const Standard_Real aTol, Standard_Real &DMin)
 Matches the coordinates X, Y with the entity found at
that point within the tolerance aTol and the minimum depth DMin.
You must redefine this function for every inheriting entity.
You will have to call this framework inside the redefined function.

Standard_Boolean Matches (const Standard_Real XMin, const Standard_Real YMin, const Standard_Real XMax, const Standard_Real YMax, const Standard_Real aTol)
 Matches the box defined by the coordinates Xmin,
Ymin, Xmax, Ymax with the entity found at that point
within the tolerance aTol.
Xmin, YMin define the minimum point in the lower left
hand corner of the box, and XMax, YMax define the
maximum point in the upper right hand corner of the box.
You must redefine this function for every inheriting entity.
You will have to call this framework inside the redefined function.

virtual Standard_Boolean Matches (const TColgp_Array1OfPnt2d &Polyline, const Bnd_Box2d &aBox, const Standard_Real aTol)
 prevents from hiding virtual methods...

Standard_Real ComputeDepth (const gp_Lin &EyeLine) const
 Returns the depth of this object on the line EyeLine.
EyeLine goes through the eye towards a point
defined by the coordinates X,Y in the function GetEyeLine.
//! gives an abcissa on <aLin> .
<aLin> represents the line going through
the eye towards an X,Y point on the screen. This Method
must return a mean Depth on this line.

Standard_Integer GetLastDetected () const
 Gets index of last detected segment

virtual void Dump (Standard_OStream &S, const Standard_Boolean FullDump=Standard_True) const
 2 options :
<FullDump> = False -> general information
<FullDump> = True -> whole informtion 3D +2d ...

virtual
Handle_Select3D_SensitiveEntity 
GetConnected (const TopLoc_Location &theLocation)
 Returns the copy of this
