This program is most useful in Autocad release 12. Postscript fonts can be used there, but don't appear in the STYLE dialog, so you have to type them in on the command-line.
After selecting a font, you can use the Preview button if you like to see how the font looks like, a new style will be created with the name of the font. We only added the most useful options in this dialog, how often do you want to place text UPSIDE-DOWN?
