Slides the view horizontally or vertically. In general, it is more convenient to use the camera move keys (Shift + Alt), however this tool lets you set certain options more precisely.
Tracking, dollying, and tumbling
The Track/dolly/tumble function combines all the World move camera functions into one tool.
To use the Track/dolly/tumble tool, select it from the View > World move camera cascading menu in the Tool Palette or click its icon.
After selecting the tool, you can use modifier keys with the mouse. The following list shows the modifier keys and related actions.
| Modifier key | Action |
|---|---|
| none | Track |
| Ctrl | Tumble |
| Alt | Dolly |
| Shift | Pick |
| Ctrl-Alt | Look at |
| Ctrl-Shift-Alt | Reset view |
When you are working on a large model, screen
updates are faster if you decrease Motion Precision in
the Preferences > Performance options
window.
These sliders let you define a view by positioning
the camera. The view is determined by the Eye position, View point
position, and Up vector end point. The nine fields
for these options contain decimal numbers. They represent, from
left to right, the X, Y, and Z coordinates for each of the three
camera parameters. To see the camera as you modify it, use WindowDisplay > Toggles > Cameras
.
The Zoom slider also takes a decimal number which defines the extent of the camera’s field of view. Values must be positive in the range of 0.2 to 179.
For orthographic windows, two of the three Eye and View values must be the same, and two of the three Eye and Up values must be the same. If they are all different or all the same, the results are unpredictable. This is because viewing operations on orthographic windows are done on the window rather than the camera of the window.
