Oh!!! So (2:3) is in polar coordinates but (2,3) is in cartesian coordinates! That's cool.

Yes! However, for some reason one has to write a unit of length in polar coordinates, that is (2:3cm), and not just (2:3). In Cartesian coordinates, the unit of length is cm by default

I've been trying for 2 days to get these files to work. I get a pgf error "shape H not found". I've been unable to diagnose the problem, except that it takes "H" from the first edge definition.

Please respond to gerheim@cox.net.
