Drawing intrinsic coordinate graphs



Hi there,
Anyone know how (possibly with an add-in package?) to draw intrinsic
coordinate graphs with Mathematica 3? Also, anyone know how to
implement a RationalQ function that tells if the supplied parameter is
rational or not, e.g.

	RationalQ[Sqrt[2]] = False
	RationalQ[1/3] = True

Thanks, cheers,
Adrian Cable.
