Hello,

Allplan uses all the available fonts in Windows.
Just add a font to the Windows font folder so that it can be used the next time Allplan is restarted.

i am unable to add these fonts! my windows font folder shows all the available fonts but when when i start Allplan i can't use them..

see allplan Help with details about using "non" Allplan fonts
