3DMax questions

Looking at the exporter, and all the sections that are needed for a model to work. I am really confused. I wish to be able to create vehicles. I am looking for a step by step procedure overview. Basically, what do i do first form the creation of the first poly to the export. I am just not getting it, and REALLY need help. I have been modeling in ver low poly around 200 in 3DMaxR4.2. Still learning it.

Thanks! For any help,

Ted
