Three dimensional tolerance simulation device, three dimensional tolerance simulation method and three dimensional tolerance simulation program

摘要

Three dimensional tolerance simulation device which does three dimensional tolerance simulation on the basis of three dimensional model which corresponds with two dimensional plan (50) being, it collates two dimensional plan and three dimensional model the tolerance information extraction section which extracts tolerance information from two dimensional plan (58) with, by projecting three dimensional model to two dimensional plan, the tolerance aspect which forms the edge of the tolerance arrangement position to which three dimensional model corresponds from tolerance arrangement position in two dimensional plan the tolerance surface specific section which specifies (56) with three dimensional tolerance model formation department which it possesses (54) with, three dimensionsThree dimensional tolerance simulation section which does the dynamic interference check of the designated model which is selected from three dimensional tolerance model three dimensional tolerance model modification section which modifies the form of three dimensional tolerance model in tolerance ratio on the basis of the tolerance information of the tolerance model (60) with, on the basis of three dimensional tolerance model (62) with it has.
