Description

The CubicBezCurve tool creates a 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.

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.

How to use

  1. Press the Draft CubicBezCurve.svg Draft CubicBezCurve button.
  2. Click a first point on the 3D view, and hold the mouse pointer.
  3. Drag the pointer to another point on the 3D view, and release the pointer.
  4. Move the pointer to another point on the 3D view to adjust the curvature of the spline, and click and hold on the point.
  5. 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.
  6. Repeat the process of clicking, holding, dragging, and releasing to add points, and create further 3rd-degree Bezier segments.
  7. Press Esc or the Close button, to complete the edition.
