Kicking off with an in‑depth look at advanced freeform modelling, this masterclass explores the full potential of surfacing tools in SOLIDWORKS 2021. The session explains how to build clean, controlled spline geometry, make effective use of curvature combs, and understand continuity levels to achieve high‑quality surfaces. Viewers are guided through creating a racing seat using boundary surfaces, trims, ruled surfaces, lofts and patches, all supported by careful sketch preparation and analysis techniques. The video demonstrates hybrid modelling, surface evaluation, and best practices for generating smooth, manufacturable forms from complex shapes, ending with thickening and detailing the finished design.
