Silly question for Aussie

I am nearly metric illiterate - can someone help me with what these window sizes mean?

I don't think cm is what that means. 51 is related to the height and the 87 is related to the width (51-87) but I don't know what units that would be.
It is closer I think to a 5'-1" x 8'7"
Is that the rough opening in feet and inches for what I would show as a 5086 ?
That can't be it either.
In any case, do they show two different units of measure on the same floor plan?
This is probably old school Aussi annotation of some kind. I like the way they separate/write the thousands so it reads as "eleven one twenty five", "seven six forty", "six one hundred" etc... I have always wondered how they say their metric dimensions on the job site.

"I said bring me a sixteen you idiot!" vs "I said bring me a four thousand seven hundred twenty nine point eight - you idiot!"

sorry steve, spoke too soon. btw Canadian Window makers sell their product in metric but call it up in feet and inches - or inches.

so that 51-87 could be a 5'-1" x 8'-7" rough opening which would be to me a 5086 ?

The Aussie builder who knows is probably laughing at me waiting to see if I can figure it out.

Steve,
I would say the numbers you refer to are window catalog / part numbers and refer to both the style and size of window and it's sashes.

Why not scale the drawing in archicad and measure?

The scan looks reasonably flat, not too much distortion around the folds.

I did that. That's how I know approximately what size the windows are.

I think is might take an Aussie Carpenter to know what those that window annotation means.

Those Aussie dimensions are millimetres, This is the standard for our construction industry.
