The fill outlines options is for display only — it is a wire-frame mode for use during the design process.
To make an outline font requires white (anticlockwise) contours inside the black (clockwise) ones.
There is a glyph transformation that will make an outline font for you if you’re using the Professional Edition or the Trial Version (the same program, but limited to 30-days use).
- Select the glyphs you wish to transform
- Copy the glyphs for later undo
- From the tools menu, select Glyph Transformer
- Click on the Open script button
- Select one of the outline transformation scripts, e.g. Outline Medium
- Click OK to execute the script
- Paste the clipboard contents back over the same glyphs
- Undo (there is no undo for transform scripts, but there is for paste)
The selected glyphs will now be outline glyphs. Examine them to see if the result is what you want, and repeat the process with a different script or different values if not.
