The VIEW POINT command allows you to change your viewing position relative to a drawing or model in AutoCAD.
To access this command you can:
type vpoint at a Command: prompt
OR
select 3D Viewpoint under the View Menu.
--Prompt: Rotate<View point><0,0,1>: Type r to select the rotate option and press Enter.
--Prompt: Enter angle in XY plane from X axis <270>: Type the
desired angle in the XY plane.
--Prompt:
Enter angle from XY plane <90>: Type desired
angle from the XY plane.
See the explanation below.
The default angle for viewing models in AutoCAD is 270 and 90 degrees. Look at the Figure below to see this orientation. You are oriented at the 270 degree point on a flat XY plane and angled at a 90 degree angle to the flat XY plane.

In the Figure below, the VIEW POINT has been changed to 300 IN the
XY plane and 35 degrees FROM the XY plane.
.
To view a model from the FRONT use 270 and 0 degrees.
To view a model from the TOP use 270 and 90 degrees.
To view a model from the RIGHT SIDE use 0 and 0 degrees.
