Use the auto-fit tool 
from the View Manipulation toolbar to quickly adjust your view of the model so that the model or model plot fills the viewport and is centered within it. When you fit a view of a model, the orientation does not change, as indicated by the view triad.
When you auto-fit an X–Y plot, the auto-fit tool resets the values in the axes to their specified minimum and maximum values; see “Customizing X–Y plot axes,” Section 47.5. The auto-fit tool does not necessarily fill the viewport with the X–Y plot, because the chart options may dictate that the plot occupy only part of the viewport; see “Customizing X–Y plot appearance,” Section 47.7, for more information about the chart sizing and positioning options.
Auto-fitting occurs in the current viewport as soon as you click the auto-fit tool. If you have more than one viewport, select the viewport that you want to rescale to make it the current viewport before selecting the auto-fit tool.
A separate option, Auto-fit after rotations, is available when you select View
Graphics Options from the main menu bar. You use this option to control whether or not Abaqus/CAE automatically rescales the view to fit the viewport as you rotate. For more information on using this option, see “Rotating the view,” Section 5.6.3.
