How to Tween 3D Properties in Flash CS5
After you have a feel for how Adobe Flash Creative Suite 5’s 3D Rotation and 3D Translation tools transform Flash CS5 movie clips, you can incorporate these effects into a motion tween to create stunning effects just as easily as you would with position and transparency.
Follow these steps to create a tween with 3D properties:
Place a single movie clip instance on a new layer on the Timeline by dragging it from the Library panel.
Right-click (Windows) or Control-click (Mac) the first frame of the new layer and choose Create Motion Tween from the contextual menu that appears.
A new tween span is created, and the playhead jumps to the end of the span.
Select the 3D Rotation tool and click the movie clip to make it active; circular handles appear around the instance.
Click and drag the axes to rotate the movie clip until you set an angle and a position.
Press the Enter or Return key to play back your timeline, and your movie clip tweens from its original 2D position to the 3D settings you applied, as shown in the figure.
Repeat Steps 3 through 5 with the 3D Translation tool to see your movie clip slide in three dimensions.
