Please see the Tutorial for the section on the **Fabrication Output** button and Gerber generation. If the problem is that you cannot see a **Fabrication Output** button then please post back with a screenshot of your PCB Editor showing the top toolbar and include type and version information about your browser. Thanks.

Forgot that the **Fabrication Output...** button has been renamed to **Gerber Output...**: ![enter image description here][1] [1]: /editor/20180101/5a4a3b1bc876f.png

Thanks, gerber output worked.
