Flood bridging pins

autodeskguest

Hi, I most likely have some setting, setup incorrectly, somewhere but I

cannot seem to figure out why the flood fill is bridging adjacent pins

vs running out traces to the flood?

Any suggestions on hat to check?

    It looks like the "width" of the polygon (which defines the thickness of

    the lines it gets drawn with) is bigger than the width of the SMD pads,

    by quite some margin. Eagle probably can't meet the clearance and

    thermal separation rules with a polygon that thick.

    Hi rob, thanks that helped a lot. Now traces are automatically coming

    out of both ends of that pad which is what i want but they are still

    bridging across the center of the pins as well.

     

    Would I use a small restrict polygon to prevent that?
