I had a problem with text tool in Eagle. Text was normal in Eagle, but when exported it was bigger than it should. That’s not good when you are sending Gerber files for manufacturing.
Here is an example:
Problem was that I was using proportional font-setting instead of vector. When exporting Gerber files, there is no support for proportional font and that’s why it happens. So, always use vector setting when you are going to export your design.
Now, text should be seen as it will be exported.
