The four standard isometric views are SW (left-front), SE (right-front), NE (right-
back), and NW (left-back). (An
isometric view
is one in which you see the object
from above — or below, but AutoCAD's standard views don't do below.)
An isometric view is an unrealistic 3D view since all lines that are parallel in
reality are also parallel in the view. In a perspective view, lines that are parallel in
reality appear to meet at a vanishing point, as parallel lines
appear
to do in reality
(think of railroad tracks heading across the prairie). The isometric views I men-
tioned previously are parallel projection views, and you can view 3D models using
those views in either the full version of AutoCAD or AutoCAD LT.

This warning is for AutoCAD LT users (users of the full version of AutoCAD
don't need to worry). As I've already pointed out, AutoCAD LT can open drawings
created in the full version. Those AutoCAD drawings can be saved with perspect-
ive projection current, and if you open such a drawing in AutoCAD LT, you can see
