Irregular smd pad shapes

btmcmahan

Okay, I've been using Eagle for a while now, but I just encountered a new challenge.  I have this inductor.  It has an irregular pad footprint.  So...how do I make an irregular shaped (SMD) pad?

I know make my own "DIY Pad" by drawing a polygon on the top layer.  And I can make a second polygon on the tCream layer.  And I can make a third slightly larger polygon for the tStop layer.  But since this isn't a "recognized" pad, how do I make the connection between my symbol & package inside the device window?

 

Am I overthinking this?  Is there some obvious solution I am missing?

    If you have version 6 or later

    See "Help/Editor Commands/PAD|SMD/Arbitrary Pad Shapes"

     

    It is similar to what you appear to have been doing. The library package

    needs to contain an SMD or Pad which is the connection point for the

    signal but the surrounding polygon or wire (all done in the package

    editor) is permitted and you don't get DRC errors later. The tStop and

    tCream still need to be created manually, in the package editor.
