VIEW HELP
PLAN  mode  is the default mode and is analogous to a  view  from 
above  the lower in the window you go the closer to the front  of 
the imaginary box behind the monitor.

ELEVATION is like a view from the front quite straight forward.

LATERAL ELEVATION  is like a view from the right hand side of the 
imaganary box so left is to the front and right is the back.

PERSPECTIVE is a toggle (on/off) that causes the view to be  seen 
in  perspective so further away things are smaller.   It  is  not 
possible to draw in this mode.
