Abstract:

Considering the fact that the intelligent transformation from garment drawing to its pattern in the intelligent clothing design, taking men’s shirt as an example, using parametric methods to study the transformation for the sleeve. The first step is to determine the key points and characteristic lines, and then to determine the values of sleeve crown height according to the one-piece sleeve’s cartographic convention. Second, combing the ratio of sleeve length between garment drawing and its pattern, the length of the relevant characteristic lines are calculated, and then the preliminary frame diagram of pattern is obtained. Finally, using the method of the B-Spline curve we construct the curves which have not yet been gotten in the preliminary frame diagram of pattern, and then figure out the coordinates of relative points of B-Spline curves through the geometry relationship. And then the parametric relationship is established, and the transformation between garment drawing and pattern of men’s shirt with one-piece sleeve is accomplished completely at last.

Key words: garment drawing, pattern, B-spline curve, parameterized design, clothing CAD
