Abstract

Purpose

In order to mass‐customize clothes, it is essential to create prototype pattern according to individual body shape. The purpose of this paper is to present a new method to generate prototype pattern based on individual three‐dimensional (3D) virtual dummy for further study on apparel customization.

Design/methodology/approach

The symmetrized preprocessing and convex hull method are employed to create a dress‐like virtual dummy based on 3D body scanning data. The corresponding structure lines of 2D prototype pattern are defined on the 3D dummy in advance and 3D dummy surface (only half) is cut into ten zones. Based on the characteristics of each surface, further subdivision was made in each zone to create 3D wireframe of garment prototype by calculating the intersection curves between the dummy surface and local planners. Via flattening geometrically 3D wireframe of each zone, final pattern of the prototype is got. Moreover, during the course of flattening of each zone, define constrained lines in advance so as to ensure the position and direction of each cutting pattern beforehand.

Findings

The paper finds that 2D cutting patterns of the prototype have been constructed from the computerized 3D dummy. The length of major structure lines for both 3D model and 2D cutting pattern remain the same. The seven out of ten of cutting patterns have area error within ±1 cm2 compared to 3D surface. Only two cutting have relatively larger error but controlled within 3 cm2.

Originality/value

The most outstanding property of the method developed is the possibility of geometrical transformation of 3D surface to 2D pattern through constructing 3D wireframe of the prototype garment, with no need to define physical‐mechanical properties of fabric used. The newly created 2D cutting patterns have the coincident construction and shape with conventional prototype and are of outstanding quality and preciseness.
