You can rotate any object just by selecting it and using the Rotate Object Marquee Handle to spin the object around its centre point. However, you may not want to rotate an object around its centre point. Instead, use the XY Origin Tool to add an origin point anywhere on a page. The object will spin around the page origin point when you click and move the Rotate Object Marquee Handle.
Ensure the object you want to rotate is located on your page, then click on the XY Origin Tool to display the origin point. Move the origin point to a new position, this will be the position that you want to be the centre of rotation. Select the object with the Select Tool, notice the XY Origin Tool button remains selected. Then, use the Rotate Object Marquee Handle to spin the object around the new origin point. When you have finished, click on the XY Origin Tool once more to remove the rotate point.
The origin point will remember its last position on a page. When you switch it on again, it will automatically appear in the same position when it was last displayed.
A group of objects will rotate about the centre point of the selected group, unless the XY Origin Tool is switched on. In this case the group will rotate around the XY origin point.
