oh yeah with this ruby you can make a model of our solar system, and then have collisions...

That's exactly what I'm trying to do.
But how can we simulate the orbit movement?
I can't figure out a way to this.
Does anyone have any idea?

Hello everyone!
My name is Taciano and I'm a Brazilian computing student.
I use SketchUp for about two years, but I consider myself way far from an advanced user, as I don't use it that often.

I've just registered here and would like to know how you guys create animations on SketchUp.
Well, with animation I mean real animation (complex models interacting with other models), not just moving cameras and physics effects.
I know one Plugin that is specifically for this, SU Animate, but it isn't free.
SketchyPhysics can do some things either, but there's so little documentation (in the Wiki) and the tutorials of it are so basic that is really hard to do a good animation without getting on code.

So, I would really appreciate if you have any suggestions on how pass from beginner to advanced.
Thanks!
