Trousers fine grading method

Abstract

The invention discloses a trousers fine grading method. Mainly, a coefficient L of equally sharing a grading number to each centimeter is calculated firstly; then upward size increment of a same part is performed according to a size x the coefficient + 1, or size reduction is performed according to the size x 1 - the coefficient; a numerical value of the basic grading part is obtained; and other part is obtained according to the numerical value of the basic grading part x a proportional relation of the two parts. According to the method, complete node data of the parts is selected more finely, so that the grading number of each centimeter and the proportional relation of zoom-in or zoom-out of the parts are detailed, and trousers are not deformed no matter what is the grading number and are improved in shape, attractiveness and comfort.

Description

technical field [0001] The invention relates to the technical field of garment processing, in particular to a fine grading method for trousers. Background technique [0002] Traditional grading, as recorded in most industrial manuals, puts the waist and hips of the same size at the same time. Practice has proved that this kind of grading is actually very unreasonable, because the bases of the original waist and hips are different, and at the same time Put the same size, this will cause the original shape to be deformed after grading, and the more you put it, the more it will be deformed, resulting in a decrease in the shape, aesthetics, and comfort of the trousers. [0003] The applicant previously submitted an invention patent for a trouser grading method. Although it is more advanced than the traditional grading method and corrected some deficiencies, the selection of nodes in that case is relatively small, and there are still some problems in the operation of computer gra...

[0002] Traditional grading, as recorded in most industrial manuals, puts the waist and hips of the same size at the same time. Practice has proved that this kind of grading is actually very unreasonable, because the bases of the original waist and hips are different, and at the same time Put the same size, this will cause the original shape to be deformed after grading, and the more you put it, the more it will be deformed, resulting in a decrease in the shape, aesthetics and comfort of the trousers

[0003] The applicant previously submitted an invention patent for a trouser grading method. Although it is more advanced than the traditional grading method and corrected some deficiencies, the selection of nodes in that case is relatively small, and there are still some problems in the operation of computer graphics. errors, so this application has refined a set of more refined grading methods in actual work
