A lane is a strip that surrounds the data. Lanes are used when the data is concentrated in specific areas with wide non-data areas around them. Each lane represents a strip of plate wrapped around the sleeve.
On the Lanes tab of the Properties palette, select a lane, and change the values in the Lane width or Offset boxes.
Click Auto-Fit to minimize the non-data area around the selected lane or lanes.
Note: You can define the size of the margin around the lane in the Preferences > Plate on Sleeve Planning > Lane auto-fit margin box.
Split Segment: Select this option to split the seam into two segments at the location of the pointer.
Center Segment: Select this option to center the seam between the data above and below it.
Center All: Select this option to center the location of all seams between the data above and below them.
With the pointer tool, select the edge of a lane and move the edge in or out.
To apply adjustments to multiple lanes at the same time, use Control+Select to select the same edge on two or more lanes, and then move the edge in or out.
