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:
SHIFT+click. If you hold down the SHIFT key before you click the Zoom
tool on a wheel, the current view is zoomed out by a factor of 25 percent.
Zooming is performed from the current location of the cursor, and not the
current pivot point.
NOTE When 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.
CTRL+click. If you hold down the CTRL key before you click the Zoom tool
on a wheel, the current view is zoomed in by a factor of 25 percent.
Zooming is performed from the current pivot point, and not the location
of the cursor.
Click and drag. If you click the Zoom tool and hold down the button on
your pointing device, you can adjust the magnification of the model by
dragging up and down.
CTRL+click and drag. When using the Full Navigation wheels or the mini
View Object wheel, you can control the target point used by the Zoom
tool. By holding down the CTRL key, the Zoom tool uses the location of
the previous pivot point defined by the Zoom, Orbit, or Center tool.
NOTE When 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.
NOTE When 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.
