Hi Brent, sometime ago I had to do a similar thing creating meridians and parallels for worldwide charts. The only way to do it is by using bordering points such as -89.99 89.99. Note though that some drawing packages will have difficulty displaying this sort of lines. For instance, QGis is unable to correctly draw a line coming from the projection centre in an azimuthal projection, e.g. drawing a meridian starting at the south pole in a south pole centred projection.
