how do you create pads with an oval slot hole?

autodeskguest

I'm trying to create PCB footprints for some parts that use an oval shape

slot hole for snap-in mounting.

 

The standard pad menu only seems to offer circular holes.  How can I define

an oval slot-type cut?

 

Thanks!

    Maybe the first question is: how will your board house make these oval

    holes ?

    Probably need a milling process, in which case you could put a pad and

    then mill in the middle of it ?

    ...and if so the manufacturer need one gerber with milling traces to

    mill before plating (metallised holes), and one to mill after plating

    (non-metallised holes) if you have holes/slots of both types.
