No, probably 1.5 cm's or so. Dont have my camera with me at work, but I can take some when I am home. I mean when I slide the crank arm on the BB spindle, it doesnt slide all the way down, leaving some space between the crank arm and the frame. This is confusing because the first square tapered BB I have used but what yummygooey said makes sense.. As for chainline, my chain hasn't come in yet because the bike is slowly being built, so can't check it yet.
