VPORTS
Creates multiple viewports in model space or paper space.
ZOOM
Increases or decreases the magnification of the view in the current viewport.
Control the 3D Projection Style
You can view both parallel and perspective projection of a 3D model.
Overview of Parallel and Perspective Views
You can create realistic visual effects in a drawing by defining either parallel
or perspective projections of a model.
The difference between perspective views and parallel projections is that
perspective views require a distance between a theoretical camera and target
point. Small distances produce severe perspective effects; large distances
produce mild effects.
The following illustration shows the same model in both a parallel projection
and perspective projection. Both are based on the same viewing direction.

3DORBIT
Rotates the view in 3D space, but constrained to horizontal and vertical orbit
only.
