I've been searching all over the internet and can't find a tutorial or video that really shows what I'm trying to do. I'm making sheet metal parts, but my parts are made up of multiple parts, and all those parts have to be designed together.

I also think I want the "top-down" approach, I think that is the correct term.. We know what the finished part should look like, and would like to model the part, and then break it down into its separate parts.
