Just what the title says. Help me with it, please!

There are a few tutorials on you tube to help with this.
You will need a modeling program of some sort like Google sketeup

You will also need some plugins ( download links below )

RCT3 tile

Heres the tutorial i followed. toofpikk Post is also a great tutorial!

I will warn you though Chim, it is really hard to start off with. You need alot of patience and be able to start with simple tasks before actually making really good versitile sets. I'm still only making cut outs and stuff, but it takes me ages.
You can't just whip out a 3D mega awesome animated robot after 5 minutes in sketchup. Took me a good couple hours to fully import and model my first CS piece, (a station support for a maurer spinner)
It's not easy, and no offense but baring in mind your age you may not be able to handle it just yet.

Thanks guys!!! I'm getting started.
