How do I start digitizing a field from scratch
Let's say that you've located your area of interest, and would like to start digitizing fields from scratch.
How do we go about?
Step 1. Make sure that the 'Fields Producer' layer is on
Click on the Fields producer layer (makes it Active), and make the sure that the eye is turned on (visible) -> 
learn more about a Layer's status
All the tools that you will use for digitizing layers, will be available from the 
Edit Menu on the right side.
Click on the Edit Menu , and then start digitizing with the 
Add New Object tool. Start adding nodes and digitize the field as shown in the figures. Finish with a double click in the last node, or after placing the last node, do a right-click.
If you'd like to edit the field, you may use the 
Edit_object tool, which shows how nodes are added/modified/deleted while you digitize.
