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:
- 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.
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.
- 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.
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.
