Define a Parallel Projection
You can define a parallel projection.
To determine the point or angle in model space, you can
■ Choose a preset 3D view from the View toolbar.
■ Enter a coordinate or angles that represent your viewing location in 3D.
■ Change to a view of the XY plane of the current UCS, a saved UCS, or the
WCS.
Viewing in 3D is available only in model space. If you are working in paper
space, you cannot use 3D viewing commands such as VPOINT or PLAN to
define paper space views. The view in paper space is always a plan view. Use
the PERSPECTIVE system variable to turn off perspective views in drawings
created in AutoCAD.
Quick Reference
Commands
PLAN
Displays an orthographic view of the XY plane of a specified user coordinate
system.

Sets the viewing direction for a 3D visualization of the drawing.
System Variables
PERSPECTIVE
Specifies whether the current viewport displays a perspective view.
VIEWDIR
Stores the viewing direction in the current viewport, expressed in UCS
coordinates.
WORLDVIEW
Determines whether input to the VPOINT command is relative to the WCS
(default) or the current UCS.
