A bus is an electrical object defined by two points: a start point and an end point. When a bus is selected and the Edit tool is active, the control hooks at the ends of the segment and at its midpoint 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.

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

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

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


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