D2 (myclass; C:ParCurve; U:Real from Standard ; P: out Pnt2d; T,N: out Vec2d); ---Purpose: Computes the Point, the First and the Second derivative of -- the parametric curve C at parameter U. EpsX (myclass; C: ParCurve) ---Purpose: Returns the valuec of the parametric tolerance -- on the curve C. returns Real from Standard; NbSamples(myclass; C: ParCurve) ---Purpose: NbSamples is the number of sample point used to -- polygonise the parametric curve on its domain. returns Integer from Standard; end ParTool;
