Revolve and rotate the camera viewpoint
With a large model, screen updates caused by moving the camera are faster if you decrease Motion Precision in the [Preferences > Performance Optionstopicid=GUID-11C91BA2-CD0E-4ECA-9F58-5FE081A03C85) 
window.
Revolve the camera around the center of interest
Place the cursor in the perspective window and click a mouse button to make the window active.
In the Tool Palette, choose View > Local Move Camera > Azimuth/Elevation or click its icon.
As the cursor moves, the view rotates about the center of interest (initially the origin).
Rotate the camera horizontally (yaw) or vertically (pitch)
Yaw/Pitch can be used only in a Perspective window. It does not apply to orthographic windows. Yaw/Pitch is always relative to the current position.
- Place the cursor in the perspective window and click a mouse button to make the window active.
- In the Tool Palette, choose View > Local Move Camera > Yaw/Pitch

The view rotates about the center of interest, which is the viewpoint of the perspective camera. To set the camera’s viewpoint select WindowDisplay > Toggles > Cameras 
to display the perspective window camera. When you can see the camera, the viewpoint can be picked using Pick > Component 
, and then positioned by selecting Transform > Move 
.
To identify a particular point as the center of interest, move the camera’s view icon so that the target end is at that point of interest. Subsequent manipulation of the camera with Azimuth/Elevation now keeps that point in the center of the view.
Use the keyboard to move the camera
To revolve the camera, type the azimuth and elevation angles at the system prompt:
- A positive azimuth moves the camera around to the left.
- A positive elevation moves the camera up under the scene.
To rotate the camera, type the yaw and pitch angles at the system prompt. Type the angles separated by a space or comma, and press
.
Use cursor keys to move the camera
You can use the four arrow cursor keys (
