Modeling
Shade's Create: Tool Set lets you start with all the standard primitives, or create entirely new Curved Surface or Poly Mesh models. Shade also has model automation tools and plugins that gives you a head start, including new tools for to let you accomplish more, faster.
Shade 12 introduces new mirror modeling tools that allow you to develop a single side of a model, then duplicate geometry. You can later go back and use align vertices to straighten or adjust across mirrored geometry to create a more natural, organic effect.
Use true Boolean modeling to create new, standalone geometry with complete control over surface-subdivision. Or, add simple Boolean directives to a part to tell Shade's flexible renderer how to apply boolean logic at render time, rather than making permanent modification to your model.
