3DTools reset transform

Hi,

I'm new here to the ms forums. I've been having fun experimenting with the 3DTool http://www.codeplex.com/3DTools which is quite a useful addition to Viewport3D!

At this point I can animate a globe and change the Texture skins as well as readoff coordinates. I would now like to be able to reset the trackball transform to its original position but find that the trackball transform is read only.

Is there a way to restore the original transform to the trackball decorator without doing a navigation refresh?
