When creating/editing annotations in Creo Illustrate, there is no option for defining the font to be used. You can only specify the Font Size and Font Colour as shown:

According to PTC Support document CS116109, the default font of Arial is the only option. It would be much more flexible if users in Creo Illustrate could:
- Define a default font to use in the Creo Illustrate Options dialog box.
- Change the font for individual annotations.
