Standard_Boolean IsTangent () const
Returns TRUE if the intersection is a line of tangency between the 2 patches. More...

IntSurf_TypeTrans TransitionOnS1 () const
Returns the type of the transition of the line for the first surface. The transition is "constant" along the line. The transition is IN if the line is oriented in such a way that the system of vector (N1,N2,T) is right-handed, where N1 is the normal to the first surface at a point P, N2 is the normal to the second surface at a point P, T is the tangent to the intersection line at P. If the system of vector is left-handed, the transition is OUT. When N1 and N2 are colinear all along the intersection line, the transition will be. More...
