Unfortunately, SeditiousCanary, you are asking about a wonderful feature of autocad that I have absolutely no clue about. As much as I'd like to learn 3d, I have very little use for it at work and even less use for it at home so I just have not put forth the effort to learn any of it. Basically, what I do right now is convert paper plans to CAD plans for use by a laser cutter. One of these days when I venture into the actual designing aspect, I will probably have to learn 3d.
So, to make a very long answer a little short, sorry, no help here buddy. ;-)
