Seasonal Clo 3D specialists focus on creating 3D garment visualizations and prototypes using Clo 3D software, primarily for seasonal collections. Pattern Makers, on the other hand, develop the physical or digital patterns that form the basis of garment construction. While both roles require knowledge of garment construction and industry standards, Clo 3D specialists emphasize digital visualization and fitting, whereas Pattern Makers focus on pattern drafting and grading. Both roles are essential in the apparel industry, often collaborating during the design and production phases.
