    • A method and apparatus for specifying a three-dimensional curve having steps of entering data specifying a first projection curve (CV.sub.1) and a second projection curve (CV.sub.2) is obtained when a three-dimensional curve (31a) is projected onto two adjacent planes (e.g., an XY plane and a YZ plane) in a rectangular coordinate system. The method also includes finding coordinate values (a.sub.i, b.sub.i) of an i-th (i=1, 2 . . . ) partition point P.sub.i from among partition points partitioning the first projection curve (CV.sub.1) into a number of line segments and finding coordinate values (b.sub.i,c.sub.i) of a point Q.sub.i on the second projection curve (CV.sub.2) having a coordinate value b.sub.i on a common axis (Y axis) among coordinate axes of the two adjacent planes. The three-dimensional curve (31a) is specified by a collection of points (R.sub.i) having the three-dimensional coordinate values (a.sub.i, b.sub.i, c.sub.i).

    • A curved surface generation method well-suited for application to the preparation of a numerical control tape used in the numerically controlled machining of a three-dimensional body such as a three-dimensional mold. The surface creation method includes steps of defining, on a first section curve or reference curve of a three-dimensional curved body, a point Pi (i=1,2 . . . ) which corresponds to a point Qi (i=1,2 . . . ) on a second section curve or reference curve, and generating an intermediate section curve in accordance with the established correspondence. A curved surface is created by collecting a plurality of the intermediate section curves together. Accordingly, the invention raises the degree of freedom with which a curved surface is created, and enables the accurate creation of a curved surface featuring subtle changes, allowing the precise machining of a three-dimensional body.
