DPC is achieved with SHIMA SEIKI’s APEXFiz® subscription-based design software, which digitally supports the creative side of fashion from planning and design to realistic textile simulation and 3D virtual sampling for flat knitting. Using scanned data of actual yarn, digital products created on APEXFiz® are a digitized version of sample making that are accurate enough to be used effectively as 3D prototypes, replacing physical sampling and consequently reducing time, cost and material that otherwise go to waste. When a design is approved for production, knitting data which is automatically generated can be converted easily into machine data, for real-world production of digitally developed products. As with knit simulations, fabric simulations of other types of textiles such as weaving, circular knitting, printing and embroidery are also very realistic, and many users opt to utilize APEXFiz® alongside other 3D software. APEXFiz® promotes automation and labor-savings from product development to prototyping and production in many areas, thereby contributing to digitalization and sustainability for supply chains across several different disciplines.
