Lors de l’ajout de courbes, il existe quelques options communes comme pour les autres Objets.

En Mode Objet/Édition, le menu Add Surface offre six différentes primitives de surfaces :

Primitives de courbes NURBS.

NURBS Curve

Adds an generic curve of four control points forming an arc.

NURBS Circle

Adds an a closed loop of control point forming a circle. Note, a circle NURBS surface is never filled, unlike its « real » curve counterpart…

NURBS Surface

Adds a generic surface patch consisting of a 4×4 grid plane with the center grid slightly raised.

NURBS Cylinder

Adds an open end cylinder, consisting of an extruded NURBS Circle.

NURBS Sphere

Adds a generic sphere constructed by revolving a grid of control points about an axis.

NURBS Torus

Adds a doughnut-shaped primitive created by rotating a circle around an axis.
