You can change the current
viewpoint to a plan view of the current UCS, a previously saved
UCS, or the WCS.
A
plan view is a view aimed toward the origin (0,0,0) from a point
on the positive Z axis. This results in a view
of the XY plane.
You can
restore the view and coordinate system that is the default for most drawings
by setting the UCS orientation to World and then setting the 3D view
to Plan View.
CommandsDVIEW
Defines parallel projection
or perspective views by using a camera and target.
PLAN
Displays an orthographic
view of the XY plane of a specified user coordinate system.
System VariablesBACKZ
Stores the back clipping
plane offset from the target plane for the current viewport, in
drawing units.
FRONTZ
Stores the front clipping
plane offset from the target plane for the current viewport, in
drawing units.
VIEWDIR
Stores the viewing direction
in the current viewport, expressed in UCS coordinates.
VIEWTWIST
Stores the view rotation
angle for the current viewport measured relative to the WCS.
