Glad it's working for you. To answer your question, I'm not that smart. Just ask the guy sitting next to me. However, I've gotten pretty good at this job by constantly seeking out people that know more than I do and yes... asking lots of questions. Seeking out online tutorials, both free and those I have to buy. When I bought a DVD of tutorials for Real Flow, I couldn't decide if it was worth the $80 or so. Since then I've made tons of money doing Real Flow sims. Sometimes it's worth it to buy DVDs and books.

Good luck to you.
