PURPOSE:To improve the operation efficiency of a bent part at the time of generating a developing shape and to enable an operator to easily and highly precisely prepare the developing shape. CONSTITUTION:This CAD/CAM device is provided with a sheet model defining part 4 for defining a plate-like product shape by a sheet model having no thickness, a sheet model editing part 6 for editing the sheet model by specifying a notched shape, a solid model converting part 7 for generating a solid model by thickening the sheet model, a solid model defining part 9 for defining a solid model with thickness, a solid model editing part 10 for editing the solid model by operation, an interference checking part 11 for retrieving the interference of a model, and a development shape generating part 12a for developing the solid model to generate a developing shape model.
