Abstract: Abstract:This study based on the prototype contour design requirements, selected the body angle as measurement,including shoulder angle,back into the corner, back side angle, chest convex angle and so on.Using 18～28 years old in college school female students as model, and the reverse engineering software imageware12.0 as a important tool,gaining three dimensional human body’s point cloud data. According to the coordinates of points, calculate the body surface of different angle.After analysis the data, determine the significant angle.The purpose of this study is to create the corresponding relationship of surface angle and the prototype dart’s angle, converting angle’s parameter into garment structural parameters, so that the angle parameter is introduced the design of the prototype.Improving the fit of the garment further, and provide support for the design method of prototype by using angle and the body’s data.
