Abstract:

n order to making the bottom design more fit, in this paper, based on the non-contact 3 d body scanner measure 200 female students from college, getting the design data relation to hips bottom design. Using the SPSS data analysis software to clustering different hip shape (mainly the shape of hip convex and its curve extent)；Then using OptiTex3-D CAD to establish different models which have different hip convex, then suing three-dimensional cutting with these models getting different body pants pattern. Through comparing and measuring these patterns, analyzing the effect of different hip convex on pattern, such as the change of boilerplate’s province, the curve bending of crotch and the displacement changes of important technological points. At last, summarizing the rules of structure change which will has important guiding significance to the pattern design for special shape.

Key words: change of boilerplate&rsquo, s province
