%A %T A New Method to Obtain the Intersection Point %0 Journal Article %D 2007 %J Science & Technology Review %R %P 60-63 %V 25 %N 0702 %U {http://www.kjdb.org/CN/abstract/article_105.shtml} %8 2007-01-25 %X In some cases, the control points can not be introduced for rapid visibility at the intersection point with the construction molding method and additional control points should be used. In this paper, it is proposed that the intersection points of rear edges and corners are calculated to deduce the desired intersection points. High precision coordinates can be obtained.
