There are three basic transformations from which any other transformation can be obtained.They change the orientation,size and shape… Read more »
Grading
The purpose of grading is to create patterns in different standard sizes. Grading a pattern is really scaling a pattern up or down in order to adjust it for multiple sizes. Pattern sizes can be large, medium and small or else there are standard patterns of size 10, 12, 14, 16 and so on for different figure and statures sizes. This is generally how we get S M L XL XXL sizing. Pattern grading by manual method is a cumbersome task because the grader has to alter the pattern on each and every point from armhole, to neckline, sleeve cap and wrist etc. by using CAD it is much easier and faster.
