Edit Custom Additions... (Additions Menu)

This command opens a dialog window that displays the various custom additions that have been added. You will see the name of each addition and its current width. As you will see, this is where the name of an addition appears, so it is wise to name your additions with regards to their position on the garment. If you do not name an addition as you add it, Designer will assign a generic name (e.g. Hem1, Hem 2, etc.)
 
If you change a width to '0', the addition will no longer exist when you click OK and go back to the main screen, so this becomes an alternate way to remove a custom addition.
