i think imma freak out...I've been working on a training material that i bought digital tutorial. Its some sort of space bike. But i model the first half of the bike...then duplicated it -1 on the x axis to combine the two to make one continuous object. But the training DVD that I have is scratched only in that 1 minute section so I can see how to do it. So i started exploring. I found the combine edges tool but i cant that to work to save my life...and when it actually does something it deforms the faces one side. I also tried merging vertice but it will only merge certain ones, so when i convert from poly to subD two points that need to be connected aren't. Its a very frustrating task that seems like its easier than i making it...but i just dont know the correct steps.
