Before proceeding to Gerber and NC Drill files generation, a DRC (Design Rules Check) must be performed in order to check your layout respects all the manufacturing constraints.
In Altium Designer Select : Tools / Design Rule Check and run the DRC. Correct all possible errors before proceeding to the next steps.
Generating Gerber File
In PCB view, select : File / Fabrication Output / Gerber files which will open a popup window.
• Select “Used On” in Plot Layers • Select “All Off” in Mirror Layers • Check “include unconnected mid-layer pads” • Uncheck all in Mechanical Layers to Add to All plot
