<P>PROBLEM TO BE SOLVED: To solve the problem in which a two-dimensional drawing can be created from a three-dimensional model by projection but in a two-dimensional drawing, hidden line processing or how to write a dimension line is determined in accordance with an application so that, by only the projection of a shape, the quantity of work of correction/addition by manual work becomes large. <P>SOLUTION: In a corresponding information extraction section, shape information of a three-dimensional model and a two-dimensional model is made correspondent to drawing modification information comprised of a dimension line or hidden line processing. Thus, in the case where the three-dimensional model is corrected, the drawing modification information is also changed in response to a change of the shape information, thereby reducing manual addition or change work of the drawing modification information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
