The power and ease of subdivision modeling with the precision of NURBS
T-Splines introduces new subdivision surface type workflows into Rhino's precision environment. These workflows, enjoyed for their rapid concept generation by animators, bring the same speed benefit to industrial design. And, for the first time, T-Splines makes them available in a NURBS-compatible, production quality way.
Box modeling tools
Box modeling or polygonal modeling is a method where the designer pushes or pulls on and extrudes basic shapes to quickly rough out a desired form. T-Spines makes this technique available for the first time in a NURBS compatible method. Box modeling can begin from a single primitive, like a cube, or by deriving a T-Spline model from polylines.
Extrude shapes: Modify your model by adding geometry and dragging faces, edges, or vertices.
Local detail: Create local detail in a surface with no need to extend the detail across the whole surface.
Control points: Add control points anywhere on the surface.
Manipulator: fully control the extent and direction of extrusions of individual or groups of points and edges. Macros allow quick and easy selection of logical groups of surface points.

It could not be easier to create the shape you need. Start with a mesh box, or lay out your own starting shape with polylines. Next, pull on faces to add geometry, insert more control, and generate a smooth model with no gaps or blends.
