Curve

With the Curve tool you can create freeform NURBS curves, trim curves, NURBS surfaces and extruded NURBS objects with freeform intersection, polygons, polyhedrons, polymids, and mesh map objects. The tool can also be used for 3D painting freeform curves to underlying objects that have bitmap textures.

The first option of the curve tool, Class, let's you choose what kind of objects to create.

Geometry - Creates an analytic polygon, polymid, polyhedron, or a NURBS curve or a NURBS mesh.

Type:

Map - Creates a mesh mapping.

Trim Curve - Creates a trim curve. A NURBS mesh must be selected.

3D Paint - Paints curves to underlying objects that have bitmap textures.
