Excellent..  Thank you for your response.  I'll start looking at OpenGL.  I've looked into Blender previously for simply animations and having an average user use that for any sort of interface would indeed be overwhelming.  I simply need a viewer that you could zoom and orbit.

It would also be nice if you could import an existing 3D CAD geometry for viewing.

I think I need to start downloading Python with a few of the libraries and start playing around.

Thanks
