How Do You Make Those 3D Models?

[steven]

I'm just curious which programs you use to create those 3D starship models?

Then, once you've created one on the computer, how do you make them into a small scale model for the table top or whatever?

Finally, is there a repository of files of various FASA ships available to print from or do you need to create your own from scratch or trade them or what?

Thanks.
