Taking into account that the software may have 'fixed' it to print within

Yes if you want it to be 12 feet up when it races the top.

It's that bit that stops you from falling off the side of the stairs.

Looking at building plans is always fun.

True...
Perhaps that's why part of the building is missing? Or maybe it's just
that this particular drawing only includes that part, I'm not sure.

I'm glad someone else thinks so.
I have no idea what half the stuff means, but I'm nosey anyway! ;-)

That's a tilt of a tad more than 4°, but essentially yes. ;-)
(On the paper it sure looks like a perfect square. But there we are.)

Who secures stairs in place by resting them on unset concrete? :-S

I was thinking more that the *stairs* are made of concrete...

Oh you mean like one big pre-fab set of stairs? If they all shrunk 0.4mm
after they were taken out of the mold then the usual idea is to make the
mold 0.4mm bigger than needed...
Anyway, who's going to notice if the last step is 0.4mm less that the
others?

...which was why I was amused at the stairs having dimensions to the
nearest mm. ;-)
Seriously, if I take a tape measure to the finished building, do you
really think all the measurements will be exactly whole numbers of
millimeters? I somewhat doubt it. ;-)

If you give builders plans to the nearest meters, you can none of the
dimensions will be accurate to the nearest meter either. Does it all make
sense now?

No, but it's a typical value with some tolerance. On our drawings we always
have stuff that is labelled like 16.68 +/- 0.20 mm, if they made all the
parts with an average of 16.66 mm then some of them wouldn't fit together
properly.

As I understand it, the stuff you make is somewhat smaller than a
building. ;-)
