ABSTRACT
Nurbs stands for Non-Uniform Rational B-Spline which sounds like a complicated name for a complicated subject. Meta shapes or to be precise Meta objects are implicit surfaces, meaning that they are not explicitly defined by vertices or control points: they exist procedurally. Meta objects are literally mathematical formulas that are calculated on-the-fly by Blender. Nurbs Curves are entered in the 3D window by pressing Shift + A key or clicking Add in the window header and selecting from the menu that displays. With the Nurbs Circle selected in Object mode the shape may be expanded by settings in the Properties window, Data buttons, Geometry tab. The Nurbs curve is the starting place for creating shapes, objects or animation paths. Lofting is sometimes referred to as Lathing which is the process of generating shapes using Curves. The shape is generated then converted to a Mesh Object.
