const Standard_Boolean  cutting = Standard_False,
const AppParCurves_Constraint  FirstC = AppParCurves_TangencyPoint,
const AppParCurves_Constraint  LastC = AppParCurves_TangencyPoint 
)

The MultiLine <Line> will be approximated until tolerances will be reached. The approximation will be done from degreemin to degreemax with a cutting if the corresponding boolean is True.
