Appears when the Rotate command is active, and allows you to either observe rotation options as you rotate an item or specify rotation options.
Copy
Creates a copy of the item that you are rotating.
Position Angle
Displays the angle between the horizontal axis through the center of rotation (A) and the point that you rotate from (B). Then, if you rotate the item, the position angle (C) changes to become the angle between the horizontal axis and the point to which you rotate. The position angle is always a positive value measured counter-clockwise from the axis.
Rotation Angle
Defines the rotation angle. The rotation angle is the angle between the point from which you rotate and the point to which you rotate. In the following picture, the center of rotation (A) shows the point (B) from which you rotate the item.
The rotation angle (C) is the angle of change between the old and new positions of the rotated item. The value is always positive.
Step Angle
Specifies the rotation step angle. The step angle specifies the increments, in degrees, that an item rotates on a rotation axis. You can enter increments in the Step Angle box. For example, if the box is set to 30.0, the rotation is displayed in 30 degree increments. The default setting is 0 degrees so that the rotation is fully dynamic.
