Descrizione

Lo strumento Curva di Bézier cubica crea unaCurva di Bézier di terzo grado. Questa è una delle curve di Bezier più usate. Questo strumento consente di creare una grande spline composta da diversi segmenti Bezier di 3° grado, in un modo simile allo strumento Bezier in Inkscape. Una curva di Bezier di qualsiasi grado può essere creata con lo strumento Curva di Bézier.

The Draft BezCurve and the Draft CubicBezCurve tools use control points to define the direction of the curve; on the other hand the Draft BSpline tool specifies the exact points through which the curve will go.

Cubic Bezier curve defined by three control points

How to use

Press the Draft CubicBezCurve button.
Click a first point on the 3D view, and hold the mouse pointer.
Drag the pointer to another point on the 3D view, and release the pointer.
Move the pointer to another point on the 3D view to adjust the curvature of the spline, and click and hold on the point.
Move the pointer to another point on the 3D view to adjust the final curvature of the spline, and then release the pointer. This creates a Bezier curve of 3rd degree, and continues drawing from the last point.
Repeat the process of clicking, holding, dragging, and releasing to add points, and create further 3rd-degree Bezier segments.
Press Esc or the Close button, to complete the edition.

 ==Descrizione==
-The [[Draft CubicBezCurve|CubicBezCurve]] tool creates a [http://en.wikipedia.org/wiki/Bezier_curve Bezier Curve] of third degree. This is one of the most commonly used Bezier curves. This tool allows you to create a big spline made of several 3rd-degree Bezier segments, in a way that is similar to the Bezier tool in Inkscape. A Bezier curve of any degree can be created with [[Draft BezCurve|Draft BezCurve]].
