METHOD FOR CREATING THREE-DIMENSIONAL SHAPE DATA, APPARATUS FOR CREATING THREE-DIMENSIONAL SHAPE DATA, AND CORRESPONDING COMPUTER - READABLE STORAGE MEDIUM

摘要

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 (step S 140). 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 (step S150), 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 (step S 160).
