How to 'disable' 3D in main stage?

Question

Hello,
I am relatively new to Adobe Flash and have been enjoying it so far!  However, I seem to have hit a stumbling block.  I am using nested movie clips to display a moving button on the main stage.  In a nutshell, the button says "play" and uses 3D tools in nested layers to make it rotate back and forth.  It is not very complex 3D.
The problem is that when I drag this button from the library into the main stage, I have to keep it in the middle of the scene, otherwise it skews out of proportion.  For example, if I drag it to the right of the scene, it seems as if I am viewing it from its left side.  I just want the button to always appear 'straight on,' no matter where I drag it on the main timeline. 
Is this possible?  I can try to be more specific, if I it is too confusing.  Thank you very much for your help!
Here are 2 pictures to help illustrate what I am trying to say.  I want the "play" button on the first image to always look like that, even if I drag it to the right of the main stage:

use your button's prospectiveProjection property's projectionCenter to change it to the button's center.  for example, if your button is b:
var pp:PerspectiveProjection = new PerspectiveProjection();
pp.projectionCenter = new Point(b.width/2,b.height/2);
b.transform.perspectiveProjection = pp
