Adobe Flash-motion tween

In actionscript3 we created a closed line with pen tool and a shape on other layer.

Then made a converted a shape to movieclip and gave it an instance name. Then right clicked on shape layer and created classic motion guide and it created another layer after that I selected closed line layer and dragged it in newly created layer. Then extended animation by creating key frames on each layer at 60 frame and moved. Then created classic tweens for shape layer so that shape would move in circles following closed line.
