Re: gEDA-user: Pad area as heatsink

["Mike Hansen" <mehansen10@xxxxxxxxxxx>]

I tried that but as I understand it to make the pad one of the pins it has 
to be a line for a SMT part.  I couldn't make the line any wider than 6.3mm, 
PCB wouldn't let me make it any wider.   Is there a setting I have to change 
to make the top end of the line width larger?

TIA
