This article describes the use of three-dimensional (3D) software in zero-waste fashion design, with a focus on its application in the context of the authors' research and experience in industry and education. It expands on its use in visualisation for merchandising and marketing, to discuss how as a hybrid design and prototyping tool, 3D software could transform zero-waste design in industry, education and research. This research uses an experimental design approach and reflects on the authors' design process before using 3D software, and its transformation upon learning, due to its utility for holistic 2D/3D practices. The article explores a range of examples of 3D software in use, revealing new design workflows that it allows for in articulating the relationship between form, pattern cutting and wasteand concludes that the advantages of 3D software to augment the garment design process is particularly evident for zero-waste fashion design.
