Latitude and Longitude lines in AutoCAD 3D
This AutoCAD 2000 drawing has all the integer latitude and longitude lines for the earth. It also has a solid object for the earth, to prevent seeing the lines on the other side of the earth. You may wish to turn off the earth layer.
I created the drawing not in a 3D view, and then only turned on the 3D view at the end. I forget how to turn off the 3D view, you may want to do so.
All curved lines have a radius of 3958.33 units to represent the radius of the earth in miles.
