Create 2 circles centered on origin, one oriented up and down, for latitudes, one at the equator.
Use array circular copy to make latitudes...
(array circular copy doesn't create the right circles if there is only one.)
To make the longitudes:.....
Probably several ways.
One way is to draw a line from the south pole to the north pole through the center of the earth.
Use array dir to copy the equator several times, up towards the north pole, and then scale each to size along the greenwich meridian.
(Maybe use lineweb...)
oops, got the words latitude and longitude backwards...(But the points on one
longitude are at different latitudes, when doing a script...)
