Viewports are areas that display different views of your model. As you work
on the Model layout, you can split the drawing area into one or more adjacent
rectangular views known as model space viewports. In large or complex drawings,
displaying different views reduces the time needed to zoom or pan in a single
view. Also, errors you might miss in one view may be apparent in the others.
Viewports created on the Model layout completely fill the drawing area and
do not overlap. As you make changes in one viewport, the others are updated
simultaneously. Three model space viewports are shown in the illustration.
You can also create viewports on a named (paper space) layout. You use those
viewports, called layout viewports, to arrange the views of your drawing on a
sheet. You can move and resize layout viewports. By using layout viewports,
you have more control over the display; for example, you can freeze certain
layers in one layout viewport without affecting the others. For more
information about layouts and layout viewports, see

Use Model Space Viewports
With model space viewports, you can do the following:
 Pan; zoom; set Snap, Grid, and UCS icon modes; and restore named views.
 Save user coordinate system orientations with individual viewports.
 Draw from one viewport to another when executing a command.
