Again you are most observant Abd... The problem I encountered was the removal of the net from the pad used for mounting. And if it was a component, as many of our older designs were, the macros marked it for deletion. I believe I was using service pack 5 at the time... I am now using SP6 and your comments prompted me to check out this behavior myself again. I placed a free pad on an existing board and gave it a net to ground much as I would in a normal design... associated the board with the netlist and it ignored the pad. No attempt to delete it or to remove the net from it was made by the program. So apparently as long as the mounting holes are free pads without being a component the netlist macro generator will ignore them... nice. I just need to make sure that the older designs do not have the mounting holes as components... :) - Bill Brooks

Free pads, by definition, do not appear on the schematic. I read this post from Mr. Beavis and was pretty shocked. I was about to start railing at the programmers who would allow Free-padname to be deleted as if it were a component. But I tried it first. I could not get free pads to disappear from a PCB when the PCB was Updated from a schematic. If one uses a component for mounting holes, yes, that component should be on the schematic or it will be deleted.
