Everyone loves to dress up and seek to match the appearance of new fashion trends.But few people think that by style and color depends not all.It is important that, as clothing "sitting" on the figure.The right fit, the appropriate size - a guarantee of getting the perfect dress for sewing.For this purpose, gradation is applied.This change in the basic patterns for the construction of different and more precise patterns.
methods graduation
Today the technical reproduction of patterns is carried out in three ways: radiation, a way of grouping and proportional-estimated.
Ray method is based on the fact that straight lines emanating from the focus (specific point) are conducted through the design point.Then back away from the workpiece contour at a certain distance and note the value increments.United new points form a new mold.In this way, grading is performed.This is the most simple way, but also the most inaccurate.The result depends on the choice of the reference point - focus, a different position which changes the direction of the rays.As a result, the gradation patterns get distorted.This method is best suited for modeling certain parts of corsetry and hats.
Getting patterns way of grouping based on a combination of the two sets of (extreme and average size).When building the main design point of the same name should be connected by straight lines, which, in turn, are divided into several segments.Their number corresponds to the number of sizes, which is used for gradation.This is the most viable option for complex models.
Proportional calculation method - the most common in the construction.If it points moving structural patterns occurs along lines arranged horizontally and vertically, and in accordance with the variation patterns.
increment is determined for each structural terms, defining its position with respect to the zero axis.Location of the main parts of products as follows:
- on the shelf (A) is a vertical line on the chest, horizontal - line at the armhole, on the chest or waist;
- vertical line on the back (B) coincides with the center line, or divides it in half, horizontal - similar to the shelf;
- on the sleeve (C) is a vertical line on the midline, horizontal - in several places.
automated grading - is the application of new technologies
Now, thanks to modern technology, has not carried out manually designing clothes.New grading patterns of clothing provides a high-quality Design material is entirely consistent with the required level.Thus conditions such as proportion, landing, proportionality, correspond to the original size of the base.With the help of CAD (computer-aided design) we construct patterns, modeling.Therefore there was a need for specialists in designing clothes, fluent in the latest computer technology.Progress does not stand still.It is tested at full speed 3D-modeling.What awaits us in the future?Perhaps soon eliminate the need for conventional drawing performed on the plane, they will be bulky.And the concept of "fashion" to pass to the other current level.
