Abstract
Purpose – Based on the knowledge of professional pattern makers, this paper aims to propose an expert‐based automation technique of darts generation by aligning and drawing close meshes in basic pattern in Part I. Single dart development, such as waist‐fitting dart, shoulder dart, armscye dart, side dart, and their select combination are also presented.Design/methodology/approach – In this paper, 3D garment surface is first approximated by a finite number of meshes. Patterns are developed by aligning and rotating of the flattened meshes under the constraint of overlay avoidance. The envelop areas between the developed patterns and the curved surface are dramatically reduced from 5 percent of basic pattern to below 3 percent after darts development.Findings – The development patterns are varied in their association with the subject's body figures and the designed garment. Darts in a different location can reduce the total area difference between the flattening undevelopable surface and the original curved ...
