there are many tutorials for other modeling applications on the net.
those are very help for making some model with Cheetah3D, that have basic and extra fuctions for (Subdiv) polygon modeling, I think.
you can find its with Google or other search engine, or other application's page, Wings3D, Silo, Hexagon, Carrara, MAX, Cinema4D...
