Abstract
A free curved surface generating system and method in which a plurality of cross sectional curves representing cross sectional shapes in an x-y coordinate system are generated, the plurality of cross sectional curves are arranged at desired positions in the x-y-z coordinate system, respectively, and thereafter a curved surface is formed between mutually adjacent cross sectional curves through an interpolation to generate the free curved surface are disclosed. In the free curved surface generating system and method, when the parallel translations and rotations are carried out for the generated cross sectional curves in the x-y-z coordinate system, the parallel translations and rotations are stored for each cross sectional curve into a memory and each cross sectional curve is parallel translated and rotated on the basis of data on the parallel translations and rotations for the corresponding cross sectional curve stored in the memory when the cross sectional curves are moved again into the x-y-z coordinate system.
