When a track object is selected and the Edititing tool is active, the control hooks are displayed at the ends of the track and at its midpoint. If the track includes meanders other control hooks are displayed on the meanders to adjust their height and position.

When the control hooks of a track are visible, you can perform the following operations:

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

  • Activate both external hooks of a linear track and drag one of them to rotate the track around the midpoint.

  • Activate both outer hooks of an arc track and drag one of them to rotate the track around the center of the arc.

  • Activate and drag the hooks on the meanders to adjust their height and position.

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

  • Click anywhere on the track and drag the mouse to move the object.

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

SuggerimentoTip:

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