This tutorial will come in handy for those wanting to split level their homes instead of having to go an entire flight. It makes the homes look awesome. I would totally subscribe to TheSimsSupply if I were you. They’re in the process of upgrading all of their Sims 3 tutorials.
These videos come in two parts. Hopefully this will help you out some. I’m only posting this for other users who need help or a step in the right direction. I’m not going to use the CAW tool because I don’t trust it. My game runs fine [without updates/patches] and I want it to stay that way. Anyway, good luck. -Asilee
