View your Gerber files
Check your output files using this 'Reference Gerber Viewer' brought to you by Ucamco, the owners of the Gerber format.
You can use this viewer to help confirm that your Gerber data looks correct before sending it for manufacture. Just find your files in Windows explorer and drag them onto the viewer, or click the green 'Open files' to browse to the right location. Your files will then be rendered for viewing. There are tools down the left-hand side for changing the view, toggling units, and even measuring between items.
