Hi Abhay,

Michael was just talking about the techniques that you would use to model this here: http://moi3d.com/forum/index.php?webtag=MOI&msg=3612.5
just follow the links he has posted and you'll get the idea, I think the second link would suit your project. if you get stuck just post your problem with a model if you can, and the forum will be happy to help.

Cheers
