All bearing turns should have two dotted lines parallel to the start of the turn and two parallel to the end of the turn. Two of these will be on the centerline of the path, and the other two offset to the outside of the turn. If you cannot see these lines, open the Report Wizard, go to the Construction Lines page and make sure that Drag Lines are ticked.
The lines closest to the centerline of the path cannot be moved and are tangents to the entry and exit alignments. The outer lines have Adjust Side Overturn and Adjust Exit Overturn grips halfway along them.
Select the grip you wish to adjust and drag it away from or towards the other line to increase or decrease the offset. Left click to confirm the new position.
