A three-dimensional shape data creating method associates characteristic points and characteristic axes on an image of a sketch drawn by a designer, or the like, with given points and given axes in a vehicle specs box, and determines the placement position and viewpoint direction of the sketch in a three-dimensional space by selecting combinations (point and point, axis and axis, and point and axis) having the minimum error in correspondence. Then, complex surfaces of given regions depicted in the sketch are created at a time in the three-dimensional space, by forming each cross-section line in a given region depicted in the sketch from a basic line and a fillet joint line, and a fillet joint surface is created between adjacent ones of the created complex surfaces of the given regions so as to join the complex surfaces.
