<p>Method of generating a compound curved plane (201) consisting of a combination of at least two three-dimensional curved planes (201a, 201b, 201c). This compound curved plane generating method comprises a first step of inputting the data for determining each of the three-dimensional planes (201a-201c), the data for determining one intersecting line (CLi) on a predetermined plane, for example, X-Y plane (203), and rules for determining a plurality of intersecting lines on this predetermined plane on the basis of the intersecting line (CLi), a second step of determining a section curve (SCi) of the compound curved plane (201) based on a section (202) having the n-th intersecting line among the mentioned plural intersecting lines as an intersecting line with respect to the mentioned plane (203), and a third step of determining the compound curved plane (201) on the basis of an aggregate of section curves (SCi, wherein i is 1, 2, 3.....) of the sections corresponding to the above intersecting lines.</p> |
