I have a problem which is keeping me working over the holiday -the only thing keeping my board from fab. I've "tried everything" and read every Googled forum, but can't find the problem addressed (everyone wants to insulate their TO-220, not the other way around).
I have a 7805 in a TO-220 and I want the bolt hole connected directly to the ground plane ("GND") on the bottom (and the top). Eagle insists on isolating it. It seems Eagle has lots of ways to keep traces apart, but no ways to insist "I WANT COPPER HERE NO MATTER WHAT". I've edited the part, but to no avail; packages only have holes, not vias. I've even tried illegal ways, such as putting a hole on a via (didn't work). I've messed with all the DRC's (usually with bad consequences), but even that didn't fix it. If I can't solve this, I can always edit the Gerbers... p.s. NEVER had this problem with Bishop Graphics and Datak...
