Since there are some view but no answer, I'll try to explain better (I don't want even to think there isn't any answer )

Let's say I have this file:

Frame1:
Object1 xxx, yyy, zzz
Object2 xxx, yyy, zzz

Frame10:
Object1 xxx, yyy, zzz
Object2 xxx, yyy, zzz

and so on.
I want a script that moves every object (present in the project, not file related) in the right positioning, making a keyframe from every designed frame.
And that's all

I use Maya 7.0, dunno if it changes something...
