PROBLEM TO BE SOLVED: To improve the efficiency of a design operation by displaying a grid only in a range or position intended by a designer. SOLUTION: A three-dimensional grid generating part 170 acquires information to designate a range and a space for displaying a three-dimensional grid from an input device 110, and generates a 3D grid with the designated range and space. Then, a grid plane display processing part 210 acquires range/layout designation information from an input device 110, and makes a display device 150 display a 3D grid plane with the display range and layout position designated by the range/layout designation information through a display control part 140. Also, a grid plane edition processing part 220 compiles the 3D grid plane according to the instruction of the input device 110. COPYRIGHT: (C)2006,JPO&NCIPI
