Super Step and Repeat lets you duplicate items and adjust the angle, shade, scale, and skew of the copies. If you scale items, you can choose whether to scale their contents.



Using Super Step and Repeat, you can apply transformations to an object while you duplicate it. In this example the oval was rotated and scaled relative to its lower right corner as it was repeated to create a nautilus shape.
