Using lane guidance
Note – Lane guidance is only available when an SVD/SVL design has been loaded.
Use one of the following methods to select a lane:
l Position the machine with the guidance focus in the required lane and press
Select Lane. To de-select the lane, press Select Lane again.
Tip – After de-selecting a lane and moving the machine to an area of the design where
the guidance focus is no longer in the same lane, when you press Select Lane again a
different lane will be selected.
l To choose the lane boundaries, press and hold Select Lane. This enables you to
select any linework to define the lane, provided the lines do not diverge 90° or
more away from the master alignment.
To configure lane guidance and select a lane:
1. From any guidance screen, press and hold Select Lane (1).
Or from the Setup Menu – Configuration menu, select Select Lane.
If there is no master alignment in the design the following full screen warning
message is displayed.
