From the perspective of Human-factors engineering, this paper analyses three basic factors influencing garment plate type structure which are human body’s static state structure and dynamic state, three dimensional moulding methods of clothes and clothes materials and technological skills. The author proposes that margin design, dart site and the material performance in a dynamic state of human body should be paid special attention. Combined with three-dimensional cut, by means of well-designed structure lines, the techniques of garment pattern could be simplified. This research is advantageous to enterprises in stabilizing their styles in moulding pattern for enhancing their competitive power.
