Change to a view of the XY plane of the current UCS, a saved UCS, or the
WCS.
Change the 3D view dynamically with your pointing device.
Set front and back clipping planes to limit the objects being displayed.
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, DVIEW, or
PLAN to define paper space views. The view in paper space is always a plan
view.
To create a parallel projection dynamically
