About Switching Between the Model Tab and Layout Tabs
You can control how you change between the Model tab and one or more named layout
tabs.
By default, a Model tab and several named layout tabs are displayed at the bottom-left
corner of the drawing area.

Click the plus (+) icon to add more Layout tabs. Click the double-down arrow to view
more Layout tabs.
If you are working on multiple Layout tabs which get hidden , right-click the Model
or a Layout tab and select Dock Above Status Bar. The Model and Layout tab are displayed
in a separate line above the status bar.
To optimize space in the drawing area, right-click the Model or a Layout tab and select
Dock Inline With Status Bar. The Model and Layout tab are displayed inline with the
status bar.
