Zoom Tool
 
 
 

The Zoom tool adjusts the magnification of the current view of a model.

You use the Zoom tool to change the zoom magnification of a model. The following mouse click and key combinations are available to control how the Zoom tool behaves:

NoteWhen you start the Zoom tool from the Full Navigation wheel, incremental zooming must be enabled in the properties dialog box for the SteeringWheels in order to use CTRL+click and SHIFT+click.
NoteWhen you use the Zoom tool from the Full Navigation wheel or the View Object wheel, the point in the view where you click to zoom becomes the Center point for future Orbit operations until you either use the Zoom tool again or use the Center tool. If you press CTRL before you click the Zoom wedge, the Center point does not change.

Zoom Constraints

When changing the magnification of a model with the Zoom tool, you cannot zoom in any further than the focus point or out past the extents of the model. The direction you can zoom in and out is controlled by the center point set by the Center tool.
