The next important member of the NURBS family is the Sweep NURBS, which takes a spline path and sweeps a shape across it. It can be used to create very abstract and stylized designs, or it can be used to solve very practical modeling issues. The file for this recipe has a simple setup where a Sweep NURBS object is really the only way we can achieve our effect. We'll also get introduced to the handy Spline Mask feature in Cinema 4D.
