How to draw pants cutting?

First, draw the front membrane.

1. Set five vertical lines.

BC is a little more than a quarter of the hip circumference, and CD is a third of BC.

2. Find the point A which is 0.7 cm away from the edge of line C, and connect the point A with the edge vertex of line D. ..

Distance from the edge of the cloth TW/4- 1 = 17.5cm, draw a horizontal line and cross the BCD line. On the C line, measure the set point B 3.4cm above the horizontal line, and the arc connects the point B with the horizontal line, which is a small gear. Take ab/2 on the C line and set the O point. Draw a horizontal line after the o point. This is the seam in the middle.

3. On the E line, the distance between the middle horizontal line and the bottom is 8.5cm (width at knees), and on the A line, the distance between the middle horizontal line and the bottom is 7cm (width at trouser legs). The connecting lines are all front pants. Note that the line from E to C should be slightly curved.

Second, after painting the movie.

1. Draw a vertical line f from line C to 0.85cm of the trouser leg.

2. The edge of the back panel is 2 cm away from the edge of the front panel and19.5 cm away from the edge (tw/4+1). Draw a horizontal line G, and cross the line F at point H.. Measure 8.5cm (big gear) from point H to point R.. Find the E point on the F line at a distance of 1 cm from the edge of the backboard.

3. Draw a vertical line M at a distance of 2.3 cm from line B and a diagonal line from the edge of line B to line M.. The diagonal length is 18.5 cm, and it intersects with point S .. On the E line, it is 9.5cm above and below the midline (width at the rear knee), and on the A line, it is 8.5cm above and below the midline (width at the rear trouser leg).

Connecting all the points is the back picture. Note that the arc from point R to point S should not be too curved, otherwise the back butt joint will be very narrow.

Fine adjustment: measure whether the trouser legs connected before and after are the same length. If the back leg is long, move the F line to the left to adjust it. The spacing of CF lines is 1cm. Or after cutting the front piece, cut the back piece trouser legs with the same length on the back piece. A pink line (right angle) is added to the back waistline, and the waistline is an arc.
