Having executed the following command,
(First point) 0,0,0
(Second point) 10,0,10
I get a line. And that makes sense, because I am looking at the edge of it.
But if I use the navigation view, I can see the OCS rotating, but all I see is a line. Why is this? Is that because all initial drawing is only on the x-y plane, so the only thing that is actually realized is the intersection of the result of the operation and the x-y plane?
