Your turn Autodesk, tell him why is bend lines are WRONG!
Okay, it's not your fault. I will give you the bad news.
R7 line scale was based on the part scale not paper space so you had to
change the global scale to compensate. R7 SP1 fixed this problem, BUT they
hosed the bend line scale in the unfold views and frankly, I have no idea
how to fix it nor will I try.
Go back to R6 if you got it.
