Navigation Modes
There are nine navigation modes to control how you move around the main navigation view - six >camera-centric modes and three >model-centric 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, the Orbit and Examine modes essentially do the same thing, except that Orbit moves the camera around the focal point and Examine moves the model around the focal point. Movement in each mode is based on the cursor keys, the Shift and Control keys and mouse drags. The mouse wheel is also supported, allowing quick and easy zooming or tilting, depending on the current navigation mode.
Note
Dragging with the left mouse button while holding down the Control 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 Control 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.
Right clicking on any item in the main navigation view or selection tree displays a context menu that shows a list of commands relevant to a particular item.
The Navigation Mode toolbar also includes the Select tools, as they are mutually exclusive to navigation just as redlining and measuring are. See for more information on the selection tools. Below is shown the Navigation Mode toolbar and the navigation modes available:
