Animation question

Here is what I want to do. I need a flat surface to start as a small
ellipse about 3CM in dia and expand into a large ellipse about 5meters
in dia in an animation about 15 seconds long. What would you recommend?
Equation driven? I am not sure how to approach this?

Well, I suppose the obvious smartass response of "just use zoom" won't
do for this one? Seriously, it sounds like you're leaving something
out. If all you want is to change size of a 2D shape, you actually
could just use zoom. Who would know?

If you want to use Animator, you'll have to do it in context and use
assembly mates to make it work (assembly distance and angle mates are
the only numbers you can use to drive animations), so you'll probably
want to skip that.

Alternatively you could just change the sizes slowly, getting a bunch of
screen shots along the way and put them together into an animation. You
can get free trial software to do that. Maj and min axes of the elipse
could be related by an equation.

good luck,

Thanks Matt,

I guess I should have pointed out that the animation has a background
assembly that stays the same size so the zoom wont work but I think I
could do the in context assembly stuff, any examples you know of that I
could look at and dissect?

The screen capture idea is good but I am afraid of the time involved in
this if there is more than one animation to do I would rather put the
time into a in context scenario and then run it several times using the
initial time investment in that scenario instead of doing it over and
over and over...
