One question...

Theme: Package, component in PCB

How can I adapt the font size?
For components to be inserted in the future, you can set the font and the font size. In the "Settings" menu under "Settings (INI-File)" the "Fonts for symbol import" are defined.

The texts on already existing components can be changed as usual: You select the texts or the entire components and type the keyboard key [e] to edit them.
