Josh, you could try the PTC University. There may be a course on 2D drawings that covers repeat regions. There is too much to cover in a forum like this. The Help Center does have some good pages on creating repeat regions,.... the only problem is that you have to dig through a lot of pages to piece together the info you're looking for. What I did was to wade through all the pages that were related to repeat regions, and print off any that looked relevent to me. I then made a little book that I used as sort of a homemade tutorial. Good luck!
