problem with dimensions: colinear, but segments don't add up

If you look at the dimensions along the uppermost face of the wall here (just a fragment from a larger model), you'll see that 160mm + 6723.9mm + 160 mm mysteriously add up to 7042.9 mm, instead of the correct 7043.9 mm. If the smaller segments weren't colinear with the largest, they could legitimately total more, but as far as I can see they're exactly colinear. #colinearity #dimensions #measurements
