Thanks, Chris, for the link to the shape creation posting. I vaguely remember this from when I first dabbled with OG in 2002 or so. It sounds as though it would be fairly easy to make a shape out of a line, with magnets at the ends and middle.

I don't understand how one can effectively use OG without magnets. All CAD programs have "snap" features which allow one to precisely connect various parts together. Doing it by eye sounds to me like an exercise in frustration (and headache). The "snap" feature in OG uses magnets - they also have the nice feature of preserving connections when parts are moved around, which is something which is not easily done in other CAD programs.
