If it's like ACAD2000, you need to change the viewport, I think. One way to do that is UCS - New - 3, then align it via 3 points (it helps to have a cube already handy, and be looking at it at a diagonal like SW viewpoint).
I know there's an easier way, but I can't seem to recall how to change from X-Y to X-Z, Z-Y, etc.
