PROBLEM TO BE SOLVED: To reduce drawing correction after a drawing is generated in a system where the two-dimensional drawing is generated from three-dimensional data. SOLUTION: A layout is stored in an input processing 12 by the basic drawing layout (front drawing, side drawing and the like) input 11 of a user. In a candidate drawing extraction processing 14, the layout and data of a three-dimensional model data part 13 are inputted. Respective positions on three-dimensional model data, where plural drawing features (features to generate drawings as detailed drawing and cross section drawing) which are to be displayed as two-dimensional drawings exist, are extracted. A generation candidate display processing 16 displays the drawing showing the graphic feature in the extracted positions on a display device 15. A generated drawing input processing 18 is conducted by giving the instruction 17 of the generated drawing corresponding to the graphic feature by the user in accordance with display. The instructed generation drawing is generated based on the basic drawing layout and three-dimensional model data in a drawing conversion processing 19. A drawing layout processing 110 is conducted and the drawing is stored 111 as drawing data.
