Using Guidelock guidance mode
Guidelock is a coverage based guidance mode. A curve based on the existing coverage is generated, regardless of when the coverage was created. This function is extremely useful as it makes it possible to use the autosteer function around a profile or field boundary without creating or saving a curve, or to continue with autosteer from a previously treated coverage path for which a curve had not been saved. This guideline method is sometimes referred to as 'free form'.
