Might anyone have the name/source of a good engineering font for symbols -- like diameter (circle with angled line), depth (en-dash sort of line with downward arrow), and counterbalance (like a sideways bracket)?
The client's engineers suggested a font called "AIGDT." It's eluding me. I found a free site that had an engineering font that looked good, but it came with malware, and I cancelled the install. I wouldn't mind buying the font, as long as it's from a legitimate source. I'm on Mac OS X.
