Grips to Edit 2D Objects
Select the objects to copy.
Select a base grip on an 2D object by clicking the grip. The selected grip is highlighted (turns red), and the default grip mode, Stretch, is active.
Cycle through the grip modes by pressing ENTER until the grip mode you want appears (stretch, move, rotate, or scale). Choose rotate. Alternatively, you can right-click to display shortcut menu modes and options.
Next choose a basepoint.
Enter C (Copy).
Now you can make copies of your object, for example around a circle, by pointing some angles with polar tracking. Copies continue being made until you turn off grips.
Turn off grips by pressing SPACEBAR or ESC
