Abstract

This study examines the technical transition of garment silhouette development from 2D foundational pattern drafting to 3D digital simulation within the context of Digital Product Creation (DPC). Using a master basic bodice block as the structural foundation, a series of women’s dress variations ranging from contoured sheath forms to voluminous flared silhouettes were systematically developed in the CLO3D environment. The methodology applies established pattern manipulation techniques, including dart rotation, seam-line integration, and the slash-and-spread method, within a controlled digital workflow. The interaction between 2D geometric modification and 3D drape behavior was analyzed to evaluate the fidelity of virtual prototypes relative to conventional garment construction principles. Diagnostic tools, such as stress mapping and fit analysis, were employed to assess structural integrity and fit performance across variations. The results indicate that 3D virtual prototyping provides a consistent and analytically robust framework for evaluating pattern transformations, supporting improved design precision and reduced reliance on physical sampling under defined simulation conditions. However, the findings are constrained by the use of a single standardized avatar and a single fabric type, and therefore should be interpreted as condition-specific rather than broadly generalizable across diverse body morphologies, materials, or real-world production environments.
