As the topic says, I am wondering if anyone has made a mod that has introduced new units to the game yet (especially Capital Ships). I haven't been able to find any that solely integrated units into the game, but I do remember a mod that I played a long time ago that didn't necessarily add units to the game, but rather replaced them and changed just about everything, which is not necessarily what I am looking for. If anyone knows of such a mod I'd greatly appreciate your help in letting me know what I might be interested in. 
On a slightly related but different topic, I saw a website for the development for the Dawn of War mod which looks fantastic, and saw some unit designs that I was very impressed with, so I was wondering exactly how much work it takes to make units from scratch. I have 3ds Max 9, and I've never had an excuse to learn how to use it, but if I were to learn it for any reason, this would be my reason. That being said, are there any good tutorials that may be helpful in guiding me in that direction?
