Use the magnify tool 
from the toolbar to change the scale of the view in the viewport. Hold [Shift] while using the magnify tool to access the alternate magnify mode. The alternate mode moves the camera closer to or farther from the objects in the view instead of changing the magnification. The alternate mode is most useful when you use movie camera mode (for more information, see “The magnify tool,” Section 5.2.4).
To magnify or reduce the view:
From the toolbar, click the magnify tool to enter magnify mode.
Tip:
You can also select View
Magnify from the main menu or press [F4].
Position the cursor in the viewport whose view you want to change.
The cursor changes to a magnifying glass: 
Drag the cursor either left or right.
To magnify the view (zoom in), drag the cursor to the right of the starting point.
To reduce the view (zoom out), drag the cursor to the left of the starting point.
ABAQUS/CAE draws a horizontal rubberband line from the starting point as you drag the cursor across the screen. The rubberband line indicates the amount of zooming that has been applied, and the amount of zooming is proportional to only the horizontal component of your dragging motion.
Repeat Steps 2 and 3 until you achieve the desired view.
