Greetings,
  I haven't done any 3D modeling in a couple years, and have forgotten all of my Rhino, (I doubt I can make a simple box any more)  and was wondering if any of you Carrara users could answer a question on it.  It looks simple to use, (I have a HUGE Bryce background) but was wondering about the physics. I am wanting to make a movie from a model of a ball run. Create the tracks, drops, loops etc in 3D, and animate a marble running the track.
  The question is, is this something that it can do? or would I still need to hand move the marble to make the animation?  If anyone has done a video like this (it has to be the first thing most people try)  could you post a link here for me to see?
  I am designing a "real world" one for my grand kids play room, and have been wishing there was a computer "game" that allowed a construction set (like Rollercoaster Tycoon, but with marbles)
   OK, too wordy, but I think I explained what I was looking for,
      Thank you for your time,
         Rich
