Hi,
This is Moin here.
I have a schematics which is 1173.0mm length and width 18mm (tube light).
In PADS I have designed layout.
But generating Gerber is not possible as shown in the diagram 1,2,3.
Please help me in solving these issue.
You confirmed my assumption that Pads can plot larger gerber films, as every serious layout tool. A0 should be already sufficient, "OTHER" is probably allowing any plot size beyond the capabilities of your PCB manufacturer.
