Commands and options

Positioning modes

The mode specifies how angles are created when positioning segments and angles at which bus segments can be positioned. Press the TAB key to scroll through the modes or the ALT key to select the opposite mode to the active one. You can change modes at any time during segment positioning.


In all modes other than Any angle, the segment of the bus connected to the cursor shows the next segment. The segment you are currently placing precedes this segment.
