In the world of Computer-Aided Design (CAD), file compatibility is often the biggest bottleneck in production. While industry giants like AutoCAD and SolidWorks dominate the market, many specialized engineering and manufacturing sectors—particularly in Japan and East Asia—have long relied on a powerful, niche drafting tool known as HICAD.
