## Bézier Curve

Adds an open 2D Bézier curve with two control points.

## Bézier Circle

Adds a closed, circle-shaped 2D Bézier curve (made of four control points).

## NURBS Curve

Adds an open 2D NURBS curve, with four control points, with *Uniform* knots.

## NURBS Circle

Adds a closed, circle-shaped 2D NURBS curve (made of eight control points).

## 경로(Path)

Adds a NURBS open 3D curve made of five aligned control points,
with *Endpoint* knots and the *Curve Path* setting enabled.
