FreeSurf Studio

FreeSurf Studio is a free NURBS-based CAD system for complex surface modeling. It allows lofting between multiple curves, creating smoothed automotive-style body panels. A curvature analysis tool highlights transitions. Users can also define parametric constraints if needed. Output formats include IGES for advanced surfacing in other tools. While not offering FEA or rendering, FreeSurf focuses on shaping advanced surfaces for product styling. Ideal for small industrial design teams or freelancers needing a free solution for polished surfaces and curvature continuity checks.
