In this tutorial, you will see how Illustrator allows you to create series of objects by duplicating and transforming an existing object. In this example, the transformation in question is rotation and very importantly, all transformations take place with reference to the same central point.
Step 1: Create ruler guides
To allow you to easily centre everything on the same point, begin by creating vertical and horizontal ruler guides.
Choose Show Rulers from the View menu.
Drag a guide from the horizontal ruler onto the page.
Drag a guide from the vertical ruler onto the page.
The point at which the two guides intersect will be the reference point for creating and transforming objects.
