Can't list area of Window Surface less than 1m2?

[Anonymous]

I am still v8.1 user presently taking wait and see attitude toward AC's development. yet another hick up wasting days trying to figure out why in the world I can't get surface of window area less than 1m2 listed in the IS's Zone list??? The area more than 1m2 got listed and those less than 1m2 were listed as 0.00m2? There was no problem when listed under Window list, and before i finally give up trying and make do with tedious "cut and paste", can someone enlightened me how to resolve this? Thank you thank you.

That is the European standard - if a window is less than 1m2, it is not taken into consideration, only the area over 1m2 is calculated. This is because of the reveals, that are usually around 1m2

Check your IS Settings; the button is there!

Thank you Djordje, i am quite excited and have gone straight to check again the IS Settings, but frankly I just cannot find it. You will be of great help if can pin point the button.
Furthermore, if this is European standard, then why the window surface area under window list do give area that is less than 1m2?

I had tried that before, and tried again after your kind suggestion with new file this time: Update zone and preview again with several variation in decimal, then with different window types, and finally do exactly as your screen shot, but disappointingly, they all failed
I have also turned on extra accuracy at Calc Unit preference. Nothing seems to work...
Oh my, is that bug?
