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!

    I had to create oval holes in a project at work though I was using

    Altium and not Eagle.  What I did was overlap three holes so it looked

    like an oval shape.

     

    Caution /!\ Risk of breaking the drills if they actually drill on edge

    of previous hole.

     

    The board house we used was Prototron Circuits and

    they seemed to know what I wanted though they did call and ask just to

    be sure.

     

    I guess they changed the holes to a milled trace themselves?

     

    This is usual practice...

    If manufacturer see the overlaping drill they change this to mill path.

    At least if the drill is under 1mm thick. If the drill is 2.5mm or more

    they just use it. (it wont broke) If drill is im midle of that they

    usaly contact customer.
