NURBS are characterized by the Amazon. For working with curved surfaces there are a couple of useful tips: Use edit edge flow - edits the edge to match the curvature around it (it can also be enabled in the multicut tool setting to automately do it when you add a cut) Slide edge tool - moves edges along the curve (control-shift dragging works similar to it) The boundary tool in Maya allows you to use curves to create surfaces. The NURBS surface describes two type of surface which is known as point surface and control vertices. Viewport layout and shading/display options.
