Click the Green Flag to make a set of 4 concentric circles. Then a square will form around the largest circle. Once the circles are drawn, click on the circle sprite in the bottom right hand corner. Drag the clone to the spot you want it and release the mouse. From that same spot use your mouse to drag that next clone to the next spot and release. Add the circle clones to the design. Click the Space Bar key to stop all actions.
Concentric Circles have a common centre point.
