Perspective is what makes far away objects look smaller. If
you uncheck Perspective, how big an object appears does not depend
on how far away the camera is from the object. The only way to zoom
in on an object with a non-perspective camera is to change the
field of view, and that cannot be animated in SW 2006.
It will only now show the camera view animating along one axis instead of zooming in on the animation and then animating along the axis.
Why does this happen when you uncheck the perspective box?
Is this a bug?
