Predefined part list information box (field) for the edging material code
If this box is set the program looks for the edging code for the bottom length edge in this box rather than using the Edge column (quick edging).
Using the information boxes for the edge codes allows longer edge codes rather than the single letter codes of the Edge column.
The length edges mean the edges associated with the length column in the part list.
Note - at the Information box tree this box is in the Edging branch
