A Bezier curve is a graphic object defined by four points: a start point, an end point and two control points. When a curve object is selected and the Edit tool is active, the control hooks at the ends of the curve, at its midpoint, and at the control points are displayed.

When the control hooks are visible, the following operations can be performed:

  • Activate and drag one of the external hooks to change the corresponding endpoint of the curve.

  • Activate and drag one of the control hooks to change the shape of the curve.

  • Activate and drag the central hook to move the curve.

  • Click anywhere on the curve and drag the mouse to move the curve.

  • Right-click on a hook to display the corresponding menu of commands.

SuggerimentoTip:

While dragging a hook you can press the TAB key to constrain the horizontal or vertical displacement from the starting position.
