I recently submitted a board to OshPark and the power/ground layers were not connected. I asked why and I was told that the thermals were not connected to a pad on that layer for those holes.
I compared 2 boards using the same part (a mounting hole) from the same llibrary and one board shows what he is talking about and the other does not. It looks like it is there on the PCB file but it is not there in the gerbers. He says he thinks it is a cam setting. I have no idea.
I have attached two jpg files. One shows the correct connection on the gerbers and the other shows the incorrect or missing connection on the gerber.
Any help you can offer would be appreciated.
