A graphic processing system having a graphic element managing table storing the graphic information of graphic elements and a dimension-geometry constraint managing table storing the dimensional and geometric constraints for graphic elements. The system includes a dimension-geometric constraint succession judging table referred to for judging whether or not the dimensional and geometric constraints of a graphic are to be succeeded. Thereby, the system automatically determines whether the constraint information in the dimension-geometry constraint managing table can be succeeded as they are or must be deleted when editing is further applied to a graphic which has been already formed. The automatic determination is achieved by referring to the dimension-geometry constraint succession judging table which updates the constraint information without manual operation by the user.
