<p>A method capable of specifying the position of a fillet curved surface to be created on the intersection part of composite curved surfaces by the use of a program language. In this method, after the information on the composite curved surfaces and on the cutting thereof are inputted (S1, S2), and the composite curved surfaces are calculated (S3), the information whether the fillet curved surface to be inserted is either convex or concave is given to a system (S4). Then, according to the information thereof, if the content of the input is a concave curved surface (S5), the system so executes a predetermined calculation that the fillet curved surface is created in the boundary part between the curved surfaces either of which is on the side where normal vectors point (S6). On the other hand, if the content of the input is a convex curved surface, the system so executes the predetermined calculation that the fillet curved surface is created in the boundary part between the curved surfaces either or which is on the side opposite to the directions where normal vectors point (S7). <IMAGE></p> |
