Keep the edge of a figure fixed to animate it

Use the Free Transform tool to select the object. Then move the white circle (transform point) to where you want it to be fixed. Alternatively, you can enter a symbol and shift the entire contents so the registration point is registered at another space (or, really the content is what is shifting - but teh effect would be similar). 

Hi mate,

Using the Free Transform Tool (Q-tool) move the little whitre circle, which represents the Transformation point to be on the edge (your red line).
Do this in the first Keyframe, then create a second Keyframe and skew your symnol.
Then activate Classic Tween between the two keys.

Hope this helps!

Hi mate,

For something as simple as this, just move the Transformation Point to the edge.

The Transformation point is the little white circle. You can move it with the Free Transform Tool (Q-tool).

Do this first, then create a second keyframe and skew; then apply a Classic Tween.

Hope this helps!
