Is it possible to define a board cutout in a PCB footprint?
« on: December 10, 2013, 03:51:57 pm »
I often run into situations where I would like to define a board cutout in a component footprint, e.g. a notch in the edge of the board for a connector.  So far I've only been marking the hole on a mechanical layer, and then creating a new cutout on the PCB after it's exported from the schematic.  This is obviously not ideal since I need to do these each time I use the part, and would prefer to only do it once in the PCB footprint.  Is it possible, or is there some other workaround?

Place->Poligon pour cutout
Double click it, check the board cutout checkbox.
I did not test if this is working or not.
You can also place a NPTH pad and make it a slot hole.

What NANDBlog posted works.  I've used it before.  You can place board cutouts (converted from a region or a polygon pour cutout) in a footprint.  Once you place the footprint on the PCB, the board cutout will be implemented immediately.  I've never used it for edge cutouts though (instead relying on the define board shape for those areas) but it would work there as well.  If you use polygon floods on your board, you may wish to add polygon pour cutouts or add keepouts around your cutouts as well.

I've done it both ways- draw a shape, convert to region then make it board cutout, and add keepout. That usually involved fiddling with design rules to keep things happy. The second way- adding nonplated (or sometimes plated) slots, was much easier. They can also get the same numbers as adjacent "real" pads and stay invisible for the schematic symbol. Altium has a few videos on this topic- they make Planar inductors this way
