Constructor & Destructor Documentation

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

Load a Face.

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).
