Abstract
This paper develops the piece creation of Hull-structure using PC(Personal Computer) which is from CADRA of graphic program. Large-sized shipbuilding yard was carried out on the development of CNC(Computer Numerical Control) auto cutting system used in super S/W such as AUTODEF, TRIBON. But this system needs lots of expenses and high technician, and only used in large-sized shipbuilding yard, not medium-sized and small-sized shipbuilding yard. To bring up the small and medium-sized ship building yard lacking a little competitive power. Small and medium-sized shipbuilding yard need the piece creation of Hull Structure S/W which is joined with the CADRA. Therefore the piece creation of Hull-Structure S/W is developed to joined with the CADRA of graphic S/W to create the piece to be needed on as auto cutting process using PC.
