Set Model Tab Viewports
Viewports are areas that display different views of your model. As you work
on the Model tab, you can split the drawing area into one or more adjacent
rectangular views known as model 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 tab completely fill the drawing area and do
not overlap. As you make changes in one viewport, the others are updated
simultaneously. Three model viewports are shown in the illustration.
You also can create viewports on a layout tab. You use the viewports you cre-
ate there for arranging the views of your drawing on a sheet. You can move
and resize these viewports, and you also have more control over the display.
For example, you can freeze certain layers in one viewport without affecting
the others.
