This is what a novice can draw in 3D Geogebra tool. Indeed this is much, MUCH easier than 2D. However Geogebra is difficult when one wants to mark an angle on a sphere between two curved lines at an intersection. I'm yet to master this. Also, placing objects' labels is rather restricted.
Drawings like that will be used for an article that will accompany the Haversine table and SR method.
