A method is described for calculating intersections between two arbitrary surfaces. This method can be applied not only to every type of surface, but also to offset surface or envelope which is not representable in terms of a basic functional forms. In this method, all surfaces and surface data are expressed by two independent parameters. This method comprises two essential processes. The first is to detect the intersection points between two surfaces by successive unidimensional searches. The second is to trace intersection curves by solving initial value problem by using the intersection points obtained as initial points. The singular points on intersection curves can also be detected by using the same successive unidimensional searches. The algorithm presented here provides adequately accurate results.
