Computer technology plays an important role throughout the apparel manufacturing process. It is used for design and pattern making through CAD software like Lectra and Optitex. 3D prototyping allows for virtual sampling to get buyer feedback faster. CAM systems control cutting and spreading machines. CIM integrates information between production, sampling, accounting and other departments. Overall, computerization reduces time and errors, improves quality, and increases flexibility, innovation and information sharing across the industry.
