Also, how do I align things in 3d max 6? Cause if I make anything that is symmetric, I want it to be even instead of one side looking bigger than the other. I want to know how to align things or make things nice and straight. Thanks for the help.

do you even know what they mean when it says isolated vertices? your models suck if these aren't deleted, they are floating vertices that have no purpose what so ever. also yet there is a way, just convert it to editable poly the whole thing, then select the first veretx the one that you want to make it straight the whole way down, then copy the X, then paste it into the next vertex then Copy the Y, etc etc do that until you get the one you like, Z is for height and Y/X are used for both ways, just depends on how your hall is pointing, if you download my tutorial when it comes out you'll see how I do itdon't remove isolated vertices
