How can I draw Bundary?

I dont know how to draw a bundary
where, which menu or what?

First select a field to work on (new field or an existing one). Then click the icon that shows a boundary around a field. You will find an option to drive around the field and record the field boundary from the left or the right side of the implement.

There is also an option to draw a boundary on google earth, save it and later on import it to AOG.

Start the process when the tractor is on the field or if you do it in simulation mode, set the sim coordinates into the field (I guess near by works too?).
