A method for fast cutout includes such operations as measuring the parameters of a figure, determining norms using a principle of imaginary crossing of the figure by the horizontal and vertical planes, determining proportionality modules for each of the norms, correcting the scaled measuring parameters with the aid of the proportionality modules, making patterns of a back and a forepart of a shoulder element. While building a pattern of the forepart and back of the shoulder element, the line of shoulder is made by means of connecting the geometrical shoulder point with a point in the neck basis. The geometrical shoulder point for the forepart and back of the shoulder element is established at the site where the arcs cross, one of which is drawn with the radius equal to that scaled and corrected taking into account a proportionality module of the parameter of measuring the shoulder width of a guide on the figure with the centre in the neck basis. The second arc is drawn with the radius equal to the distance between points, one of which is the centre of said radius and taken on the pattern of the front or back correspondingly in the geometrical crossing point of the vertical plane, and the third is taken in the most projecting geometrical point of a shoulder on the figure. Then along the obtained shoulder line from the point in the neck basis a measuring parameter of the shoulder width on the figure, scaled and corrected, is laid taking into account the proportionality module. In said pattern of the back of the shoulder element a geometrical point of the neck basis is established at the distance equal to the parameter of measuring on the figure from the waist line to the point of the neck basis. While building the lower line of a bust dart of the forepart of the shoulder element, a point at the site where the arcs cross is preliminary determined. One of the arcs is drawn with the radius equal to the two norms with the centre in the geometrical centre of the bust, and the second arc - with the radius equal to 1/2 of the parameter of the bust curvature on the figure with the centre in said point. |
