Constructor & Destructor Documentation

IntCurvesFace_Intersector::IntCurvesFace_Intersector	(	const TopoDS_Face &	F,
		const Standard_Real	aTol
	)

 Load a Face. <br>

The Tolerance <Tol> is used to determine if the
first point of the segment is near the face. In
that case, the parameter of the intersection point
on the line can be a negative value (greater than -Tol).
