Gerber RS-274X

The current Gerber formats are RS-274X or Extended Gerber, either X1 or X2. Standard Gerber or RS-274-D is obsolete and revoked. It was superseded by RS-274X decades ago. Do not use Standard Gerber any longer. Some applications stubbornly continue to use painting (aka stroking) to create pads and copper pours. While not formally invalid painted files require more manual work and increase the risk of errors in fabrication. Painting is a relic of the days of vector photoplotters, devices as obsolete as the electrical typewriter. We urge all users and developers to banish painting from our industry.
