The tilt angle is indicated in the scene's units below (negative) or above (positive) horizontal (0) at the base of
the window.
You can use the Tilt window with the Walk tool on the navigation bar to look up and down. If your mouse has
a wheel, you can use it to adjust the tilt angle.
To toggle the Tilt window
■ Click Viewpoint tab ➤ Camera panel ➤ Show Tilt Bar .
Command entry: CTRL + F7
To roll camera up/down
■ Drag the slider up or down on the Tilt window to roll the camera.
You can also type values directly the entry box at the base of the Tilt window. A positive value rotates the
camera upwards, and a negative value rotates camera downwards. Typing 0 straightens the camera.
To roll camera left/right
■ Click the Viewpoint tab, and slide out the Camera panel.
■ Type in a value into the Roll entry box to rotate the camera around its front-to-back axis.
A positive value rotates the camera counterclockwise, and a negative value rotates it clockwise.
NOTE This value is not editable when the viewpoint up vector stays upright (that is, when you use Walk, Orbit
and Constrained Orbit navigation tools).
Move Focal Point
You can change the focal point for the camera. For the current viewpoint, use the Look At entry boxes on the
ribbon. For saved viewpoints, you can use the
Edit Viewpoint dialog box on page 161 to adjust the camera values.
You can also put the Scene View into focus mode, which effectively swivels the camera so that the point clicked
is in the center of the view. See
Focus on page 113.

1 Click the Viewpoint tab, and slide out the Camera panel.
2 Type in numerical values into the Look At entry boxes to move the camera focal point by the amount
entered.
Straighten Camera
You can straighten the camera to align with the viewpoint up vector.
When the camera position is close to the viewpoint up vector (within 13 degrees), you can use this function to
snap the camera to the appropriate axis.
TIP The same effect can be achieved by typing 0 at the base of the Tilt window.
To straighten camera
■ Click Viewpoint tab ➤ Camera panel ➤ Align Camera drop-down ➤ Straighten
.
