Orientation Constraints
The Visual Target Tuner allows you to visualize and experiment with
various orientation constraints.
Rotating the Aperture
You may "experiment" with different orientations by rotating the
aperture. First ensure that you are in the Select Mode (
in the left hand tool
bar). Then select the aperture you would like to rotate. (An
aperture is selected if it is highlighted in red.) Move the mouse to
one of the corners of the aperture. The cursor should change to this
rotate symbol: 
. While the
rotate cursor is showing, click the left mouse button and hold. As you
drag the mouse around the center of the aperture, the aperture will
rotate. The current orientation is displayed during the operation.
Release the mouse button to end the rotate operation. At the bottom
right of the image viewer the leftmost number continues to display the
chosen orientation.
Orientation Details
The Orientation Details window
allow you to type in an orientation or specify one or more orientation ranges.
