Your post is very general so it is difficult to help. If you want to model something special, tell us about it. Ask for a way how to model, and you will get different proposals. For once try them all, decide what fits your preferences and for your next model you can ask more specific questions. This forum is very responsive, if you ask for help, you get it. Fast.
