Before more advised advices :)
you can't put all your letters on the same 3DM project ordered ?

Hi Marek, well I guess you could assign the font name as the object name on the letters that you created.

To do that, after you have created the text, select it and click on the object name field in the properties panel, see item #1 listed at:
https://moi3d.com/4.0/docs/moi_command_reference11.htm#propertiespanel

If you do that then when you select that object later on that name will be displayed there.

Thanks Michael, that's the way, even when the font's name is not so easy to remember, at least the beginning of its name can be written down to the object's properties.
