The line segment 910 before the 9 th point and the 10 th point is provided with a scale, the line segment 1112 between the 11 th point and the 12 th point is provided with a scale, and the width of the dart can be adjusted by selecting the scale. a is₂’b₂' edge line and line segment d₂’c₂Between eight points are sThe '1 point, the s' 2 point, the s '3 point, the s' 4 point, the t1 point, the t2 point, the t3 point and the t4 point, wherein the s '1 point, the s' 2 point, the s '3 point and the s' 4 point are positioned on one straight line from top to bottom, and the t1 point, the t2 point, the t3 point and the t4 point are positioned on the other straight line from top to bottom. The eight points are hollowed out and can be used for adjusting the length of the dart. The middle of the line segment 9s '1 between the 9 point and the s' 1 point is hollowed out, and the two ends are not hollowed out, and the middle of the line segment 10s '1 between the 10 point and the s' 1 point is hollowed out, and the two ends are not hollowed out. The middle of the line segment 11t1 between the point 11 and the point t1 is hollow, and the two ends of the line segment 12t1 between the point 12 and the point t1 are hollow.

Based on the above structure, the principle or method of use of the set rule is exemplified as follows.

1) And designing a pattern drawing of the pair of the horn trousers, wherein the upper crotch of the pair of the horn trousers is longer than that of the prototype trousers by 1cm, and the trousers openings are wider than those of the prototype trousers by 16 cm.

In this case, the A ruler is used. The drawing steps are as follows:

step a 1: and (3) drawing ab sidelines, ac sidelines, bd sidelines and dc sidelines on the paper pattern by using the A front ruler upper plate 1.

The step is to draw the contour line of the upper plate 1 of the front ruler A. Wherein, the ab sideline is the preceding waist line of trousers, and the ac sideline is preceding upside suture ac, and the bd sideline is preceding upper crotch curved, and the dc sideline is the buttockss line.

Step a 2: and (b) placing the lower plate 2 of the front ruler A below the graph drawn in the step a1, enabling the drawn dc side line to be parallel to the ef side line of the lower plate 2 of the front ruler A, enabling the distance between the dc side line and the ef side line to be 1cm, and enabling the line A of the front ruler push-out line on the upper plate 1 of the front ruler A to be in the same straight line with the line A of the front ruler push-out line on the lower plate 2 of the front ruler A.

In the step, the position 1cm below the dc side line is measured and marked, preferably, the scaled dc side line of the upper plate 1 of the front ruler A is used for measuring, and then the side line ef of the lower plate 2 of the front ruler A is aligned with the mark line.

Step a 3: drawing ef sideline, fh sideline, h point and n by using A front ruler lower plate 2₁Line hn between points₁、n₁Point sum q₁Line segment n between points₁q₁Line en between point e and point n, line segment between point n and point qnq、q₁Line q between point and q point₁And q, connecting the d point and the f point in a smooth mode, and connecting the c point and the e point in a smooth mode.

Wherein, ef sideline is buttock sideline, fh sideline is little longmen pitch arc, line hn₁And a line segment n₁q₁The fold line of the connection is an anterior internal suture line hn₁q₁The broken line egmnq connecting the line en and the line segment nq is a front side seam line, and the line q is a rear side seam line₁q is the front leg opening line connected with q₁q-line, front ruler scale L₁The arc of (c).

And finishing the step a1 to the step a3 to draw the front piece with the required size.

Step a 4: and drawing an a 'b' sideline, an a 'c' sideline, a'd' sideline and a d 'c' sideline on the paper pattern by using the A rear ruler upper plate 3.

This step is to draw the contour line of the upper plate 3 of the rear ruler a. Wherein, the a 'b' sideline is the back waist line of trousers, the a 'c' sideline is the back upper crotch curve, the b'd' sideline is the back upper side seam, the d 'c' sideline is the back hip line.

Step a 5: and (3) placing the lower plate 4 of the rear ruler A below the graph drawn in the step a4, enabling the drawn d 'c' side line to be parallel to the e 'f' side line of the lower plate 4 of the rear ruler A, enabling the distance between the d 'c' side line and the e 'f' side line to be 1cm, and enabling the line for lifting the rear ruler A on the upper plate 3 of the rear ruler A and the line for lifting the rear ruler A on the lower plate 4 of the rear ruler A to be on the same straight line.

In the step, the position 1cm below the d 'c' sideline is measured and marked, preferably, the d 'c' sideline with scales of the A rear ruler upper plate 3 is used for measuring, and then the e 'f' sideline of the A rear ruler lower plate 4 is aligned with the mark line.

Step a 6: drawing a line g 'n', a line segment n 'q', a f 'point and n' between an e 'f' sideline, an e 'g' sideline, a g 'point and an n' point by utilizing the lower plate 4 of the rear ruler A₁'line between points f' n₁', line segment n₁’q₁’、q₁Line q between point and point q₁'q', smoothly connecting the d 'point and the f' point, and smoothly connecting the c 'point and the e' point.

Wherein the e 'f' sideline is hip line, and the e 'g' line is back crotch curved lineg 'n' q 'is a back inner seam, and a line f' n 'q' is a broken line g 'n' q 'formed by connecting g' n 'and a line segment n' q₁' and line segment n₁’q₁' connected fold line f ' h ' n₁’q₁'is a back side stitch, line q' q₁'is a rear foot line, a connecting line q' q₁' Times, conform to A front ruler Scale L₁The arc of (c).

And d, drawing the rear sheet with the required size after the steps a 4-a 6 are completed.

2) And designing a pattern drawing of the tapered trousers, wherein the waist circumference of the tapered trousers is 2cm wider than that of the prototype trousers, the upper crotch line of the tapered trousers is 1.5cm lower than that of the prototype trousers, and the leg openings of the tapered trousers are 8cm smaller than those of the prototype trousers.

In this case, ruler B is used. The drawing steps are as follows:
