PDM layout system can adjust the direction of the blade by editing the direction of the blade. In clothing production, layout is the preparation process before laying and cutting. Arrange clothing samples according to the principle of saving materials and rationality. The layout rules are: first big, then small, first main, then secondary, straight to straight, concave to convex, filling in the weft direction, and shortening in the warp direction.

When typesetting, you should keep the clothes lines straight, and you can't skew or splice the clothes lines at will in pursuit of saving materials.

Computer aided design of clothing

Clothing CAD for short. Using computer to digitize and image clothing styles and pieces, practical clothing styles and pieces can be obtained. It usually includes clothing style design system, two-dimensional clothing computer aided design (2D-CAD) system and three-dimensional clothing computer aided design (3DCAD) system.

As well as the commercial fitting mirror system and the computer aided design system of clothing production management. From the design point of view, the first three items are particularly important. In the early 1970s, the United States took the lead in launching the garment CAD system, and France, the Soviet Union, Japan, Spain, Germany, Britain, Italy and Switzerland also launched the garment CAD system one after another.

In 1980s, garment computer aided manufacturing system (garment CAM system) and garment flexible sewing system (garment FMS) were developed internationally, thus perfecting garment CAD and CAM system.
