"It can't be that hard, can it?" Ok, a little more than I expected, but I got a crude symbol to EPS converter working. It ignores things like dashed lines and filled boxes, but it does what I need. In C++, on my symbol page along with examples. No, I don't handle overbars. Yes, I know I'm the one who suggested them :-P "good enough for now"
