I'm using win10 and have made a font with fontforge that is installed and recognized by win10 and by openoffice writer (so there aren't any problems with the font as far as I can tell).
The font is empty except for the numbers 1-6 as I want to use it for just those numbers on a die.
q1: How can I add a font that isn't recognized automatically to the font list?
q2: What are the requirements for fonts to be recognized by openSCAD? How do I make sure my fonts are recognizable?
