) |
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). If aRestr = true UV bounding box of face is used to restrict it's underlined surface, otherwise surface is not restricted. If UseBToler = false then the 2d-point of intersection is classified with null-tolerance (relative to face); otherwise it's using maximium between input tolerance(aTol) and tolerances of face bounds (edges).
