Rotate Around Any Point

The Rotate Around Any Point tool is similar to the Rotate tool except that instead of rotating the selected path around its center, it rotates it around any arbitrary point. Your initial touch is that pivot point. From this selected pivot point, drag your finger to the path to rotate and press the Mark Button
You can restrict the axis of rotation using the Drag Constraint Button, and like the Rotate tool, you can freely rotate the path or rotate it in discrete steps of ½°, 1°, 2°, 3°, 4°, 5°, 12°, or 15°. The angle of rotation is displayed in the middle of the page. There is one other construction option that can be set before construction begins. On the Transformations tab there's a checkbox labeled "Create Copy" If this is enabled, a copy of the path will be created. The original path will not be affect in any way. Here’s an example of Rotate Around Any Point.
