This is more efficient than regular SubD modellers, which need to subdivide the whole surface to add detail.įreeform bodies are non-parametric, but do exist in the feature tree.
add faces and edges) in areas that require more refined surface curves. T-Splines are an extremely clever addition to subdivision modelling that uses ‘T’ points and ‘Star points’ to add detail (i.e. The biggest plus is that subdivision surfaces rarely fail, which makes complex part modelling a lot less prone to feature tree explosions.
While it’s hard to get a subdivision surface to be as accurate as a surface built using traditional sketches and surface features, subdivision surfacing is quick and intuitive. Direct modelling tools enable the quick editing of geometry without hacking back through the history tree or on imported geometry
