Abstract
This paper introduces a generation method of developable surface by manipulation （translation, scaling and rotation） of curved line and a designing method of complicated shapes by combination of generated developable surfaces. This method enables to design complicated shape constructed by combination of cylindrical surfaces and conical surfaces. At first, principle of generation of developable surface is explained. Then, some examples of designed shape are indicated. Finally, an actual paper model manufactured by development of each developable surface is explained to show feasibility of proposed method.
