PROBLEM TO BE SOLVED: To make it possible to highly accurately execute preparation and correction of a shape by executing shape data generation considering an origin. SOLUTION: The shape data processor is provided with a moving/restoring event issue part 5 for instructing the movement/restoration of shape data, a moving/restoring event extraction part 7 for extracting the shape data movement/restoration instruction, an origin extraction part 8 for extracting the origin of the shape data, an error detection part 9 for verifying a threshold by which shape data regarded as the same, an origin moving part 10 for executing at least one processing out of the movement, rotation and expansion of data and moving the origin extracted by the extraction part 8, and an origin restoration part 11 for returning the shape data related to the moved origin to the shape data related to the unmoved origin and constituted so as to obtain numerical data reducing a rounding error by the movement of the origin. Consequently highly accurate intersection/intersection line data can be prepared.
