Abstract:
In a process of preparing a sketch to be used as a pattern for custom-tailoring at least a portion of a garment from selected material to fit a human figure of predetermined dimensions, the sketch is derived from a basic configuration for the desired portion of the garment, but in which selected dimensions are chosen in accordance with a set of predetermined measurements of the torso of the wearer.

Description:
BACKGROUD OF THE INVENTION 
     The present invention relates to a basic formula for an active sketch drawing in sleeve tailoring and more particularly a basic formula to measure the figure of a human body so as to alternatively fit the differences in body figure. 
     Regular sketch drawing in tailoring is unvarying and can not discover the defect in body figure for compensation in advance, thereby misfit happens quite often and further alteration is usually required, therefore, regular layout drawing technique is not perfectly applicable in mass production. 
     The main object of the present invention is to provide a right technique in body figures&#39; measurement, and a basic formula for an active sketch drawing in sleeve tailoring so as to promote the quality, reduce the loss, and increase the productivity and the profit. 
     Another object of the present invention is to provide an active sketch drawing technique such that the dressmaker can easily handle with the variation in body figure while tailoring so as to prevent any further alteration.

     While in application, the pattern drawing formula above described is performed as follows: 
     1. For one-piece sleeve: 
     (A) Sleeve length: Extend or abstract the central line to a proper length required. 
     (B) The width of the sleeve: In a style that requires a larger size than indicated in the basic pattern, the central line can be raised up and shall not be moved down. 
     (C) Style variation: According to the length and the width of the sleeve determined and set, dart, cutting, cuttling, joining can be started as required. 
     2. For insertion of a gore (see FIGS. 6 and 7): 
     (A) Sleeve length: Extend or abstract the central line to a proper length required. 
     (B) The width of the sleeve: (1) During the sketch pattern drawing process, the distance between points (31&#34;) and (32&#34;) is to control the central line and can not be reduced. 
     (2) The insertion of the gore is arranged not to exceed the level of the armpit. The inclination of the gore is determined according to the style, the loose part at the arm line and the cross point between the front part and the back part of the body. The front length and the back length of the gore is not identical. The width of the gore is determined according to the style, but the internal side of the sleeve and the internal side of the body shall be equal. 
     (C) Style variation: According to the length and the width of the sleeve determined and set, dart, cutting, cuttling, and joining can be started as required. 
     3. For cut joining: 
     (A) The arrangement of the width and the length of the sleeve: 
     Arrange as described in the insertion of gore. 
     (B) Style variation: Bust dart be temporarily set at other place and then start to draw for armhole to match with the sleeve cap according to style required and in accordance with the side line of the other part and to meet with the cut joining line of the body. 
     According to the described basic formula, one can easily draw a sketch for sleeves to fit all figures and styles.
