■ 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.
■ SHIFT+click and drag. When using the Full Navigation wheels or the mini View Object wheel, you can zoom
in to an area of the model by dragging a rectangular window around the area you want to fit in the window.
Hold down the SHIFT key and then click and drag a window around the area in which you want to zoom.
NOTE If you hold down the CTRL key along with the SHIFT key, you can zoom in to an area of a model using a
center-based window instead of one defined by opposite corners.
■ Mouse wheel. When a wheel is displayed, scroll the mouse wheel up or down to zoom the view of the model
in or out.
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.
Classic Navigation Modes and Tools
In the Classic user interface, there are nine navigation modes available from the Navigation Mode toolbar to
control how you move around the Scene View: six camera-centric modes and three model-centric modes.
TIP You can use some of these classic navigation modes with the standard (ribbon) user interface. The Options Editor
allows you to select between old and new modes.
In a camera-centric mode, the camera moves within the scene, whereas in a model-centric mode, model moves
inside the scene. For example, orbit and examine modes essentially do the same thing, except that orbit mode
moves the camera around the focal point and examine mode moves the model around the focal point.
NOTE Navigation modes and SteeringWheels are mutually exclusive, so activating navigation mode deactivates the
current SteeringWheel menu.
Movement in each mode is based on the keyboard arrow keys, the SHIFT and CTRL keys, and mouse drags. The
mouse wheel is also supported, allowing quick and easy zooming or tilting, depending on the current navigation
mode.
TIP Dragging with the left mouse button while holding down the CTRL key performs the same actions as dragging
with the middle mouse button, which is useful if you only have a two-button mouse.
The SHIFT and CONTROL keys modify the movement, for example holding down SHIFT in walk mode speeds
up movement, and holding down CTRL in this mode, glides the camera left/right and up/down.
NOTE Gliding the camera is opposite to panning the model. Gliding is a camera-centric motion and panning is a
model-centric motion.
