Default overlay styles

Each overlay has a default Pen, Brush, Symbol (shape), and Font, which are set on the Styles tab of the Overlays dialog.

These are the Pens, Brushes, and Symbols used by graphical items whose values are set to (By Overlay) in the appropriate Properties... dialog, for example:

When an overlay is created, either using an internal dataset, a BDS file, or an FDB file, it is automatically assigned a Pen and Brush which are different from those assigned to other overlays.

This is to differentiate the individual overlays, but you can change the pen and brush of any overlay whenever you wish. Likewise the default symbol, called (dot) and the default font (Arial) can also be changed.

A scale can also be set for the overlay by checking the Overlays dialog Styles tab Scale Override checkbox and entering the required scale.
