How can I add a fiducial mark to my PCB?

    I used pads from the BGA Package instead of a circle, so that the magnetization was to the center of the pad. But I do not have solder paste on the board.

    I used this successfully for one pcb but the next board I made the gerber files generated did not have the mask for the fiducial. The difference was that the check box for adjusting the pad sizes [Pads-Only (Resist/Mask) Plot] was selected. Apparently if you want fiducials then you can't adjust the size for the mask for the pads.
