Copy
Copies the elements in the selection set. This option is not selectable if a drawing view is in the selection set.
Step Angle
Specifies the rotation step angle. The step angle specifies the increments, in degrees, that an element rotates from the rotation reference axis.
Rotation Angle
Defines the rotation to point by setting the angle of the rotation axis. The rotation angle is measured from the reference axis. Zero degrees is coincident with the reference axis; the angle increases in the counterclockwise direction.
If there are two possible to points after you set the rotation angle, you can click in the application window or use the Position Angle box to define the to point you want to use.
The rotation angle is displayed on the General Tab of the Drawing View Properties dialog box for future reference.
Position Angle
Defines the rotation from point by setting the angle of the rotation reference axis. The origin of the angle measurement is the center of rotation. Setting the position angle to 0 extends the axis horizontally toward the right of the screen, 90 extends the axis vertically toward the top, 180 extends the axis horizontally toward the left, and 270 extends the axis vertically toward the bottom.
After you have set the rotation from point and the rotation angle, you can use the Position Angle box again to set the rotation to point.
