Grading tool, the directions intersect, when the inside line is not long enough after grading, use this tool to select the inside line and press the outline of the base code. Direction moving point, used to modify the coordinate direction. Select a grading point in the box, click the reference grading line, click in the target direction, and then enter the grading amount. Slope at any coordinate, move the point toolbox to select the slope point, hold down the CTRL key at the same time, release the mouse, select the direction, right click, and enter the slope amount for confirmation. Add grading points, and hold down the SHIFT box to select grading points. When elements intersect in parallel, the box-selected grading point forms the point according to two straight lines. The scale points and lines of the elements will be graded. Use this toolbox to select multiple internal points on the same side and click the reference line of the paving profile. For the proportional point between two points, for the drawing operation with inline on the garment piece, select two points to be put, and then select two reference points that have been put. From the parallel point, the line will slope the outline, select the point in the box, and click on the same side outline to enter and confirm. Feature distance points and lines will be graded, and one or more points in the same direction will be selected in the box, and reference isolines in the same direction will be selected to input distance data.

Why grading? One is that people are tall and thin and need clothes of different sizes, and the other is to improve work efficiency and shorten time, so we should grading, so we can give another definition of clothing grading from another angle, and make another set of patterns with the shortest time and the fastest speed. Based on the intermediate code and grading principle, grading is also a pattern. Computer grading of clothing. It takes nearly a day to enlarge and reduce complex patterns, especially by hand. With the wide application of garment CAD system in garment industry, the time can be shortened to several minutes by computer method. Four elements. Clothing grading generally has four elements. The middle code is the first sample we produced in the factory, and the grade difference is the difference between adjacent codes. The grade difference is determined by the growth law, grading principle, collinearity, parallel relationship, inspection and three inspections of the human body. Whether the grade difference of the same part of the same pattern is the same, and whether the grade difference of the same part of two adjacent patterns is the same.
