Creating NURBS Curve and Surface Objects
Topics in this section
- Creating Independent Surfaces from NURBS Curve Objects
To create independent surfaces from top-level NURBS curve objects, use the Extrude and Lathe modifiers. Extrude adds height to the curve, creating a shape by sweeping it along the curve's local Z axis. Lathe creates a surface of rotation, revolving the shape along a specified axis. You can also use the Bevel and Bevel Profile modifiers on NURBS curves. - Creating NURBS Curves from Splines
You can turn a spline into a NURBS object formed of CV curves. Once converted, you can no longer edit the spline shape parametrically, but you can edit it as a NURBS object, moving CVs and so on. - Creating NURBS Surfaces from Geometric Primitives
You can turn a standard primitive into a NURBS object formed of CV surfaces. Once converted, you can no longer edit the object parametrically, but you can edit it as a NURBS object, moving CVs and so on. - Nonrelational NURBS Surfaces
Nonrelational NURBS surfaces provide a way to improve the performance of NURBS with modifiers. These are controlled by the Relational Stack toggle on the General rollout for NURBS objects. - Display Controls for NURBS Models
The checkboxes on the General rollout for a NURBS curve or surface control how the object is displayed in viewports. If all checkboxes are turned off, the NURBS object is invisible (except for the white bounding-box indicators displayed in shaded viewports when the object is selected). - Display Line Parameters for NURBS Surfaces
These parameters are contained on a single rollout at the top level of a NURBS object.
