Shrink and Motion Path...at the same time!

I have had a bit of luck with this problem. I needed an object to grow and move at the same time. It was a popup window with information pertaining to a specific section of the screen. Would work with shrinking too.

Build the shape/image. If there are multiple components, copy them into the normal state of one of the components or a shape (as opposed to grouping them). Then apply the grow or shrink animation to this shape.

Now I added a transparent shape around my original image. I then grouped my image with the new transparent shape. You need something to group with, it doesn't matter what. I chose a transparent shape so it wouldn't change the look of the image.

Apply the motion to the group. SL will apply the motion path on the group and the animation on the shape simultaneously. I found it looked better if the zoom was 0.25 seconds longer than the motion path. I found this easier and smoother than using states to change the size of the object.
