Abstract: To study the intelligent transformation between fashion design and pattern,it is proposed that an innovative concept about changing 2-D garment drawing into 2-D pattern.In current study,various methods of apparel′s expression were analyzed,and the method showing how to build the standardized garment drawing was introduced.Focused on the relationship between the garment drawing and its pattern,it obtained the mathematics model about the transformation between the standard garment drawing and its pattern on the basis of the mathematics reference model of the standardized garment drawing.Transformation of body demonstrated how to establish the reference model of body and transformation process.The sample garment was used to test the accuracy of theory,and it began to set up a digital transformation system tentatively.
