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 (page 287) 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.
DescriptionMode
Walk. Enables you to walk through the
model on a horizontal plane ensuring that
“up” is always “up”.
