Dimensioning windows to unit size

[Anonymous]

Hello everyone, I'm trying to dimensions windows by their unit size (or nominal size) and not the rough opening (or wallhole size). I know I can do it with the automatic dimensions but can;t find the way to do it manually. I was looking for an answer but couldn't find anything. Someone Knows how to do that?

Thanks in advance.
BTW I'm using Archicad 19

Go to "Nominal sizes and tolerance" in the window dbx (the first setting) & check the radio button next to "Unit dimensions".
I am still on AC18 but I don't think it has changed.

I already have it in nominal size in the windows dbx, but when I try to dimension the windows, the dimensions are from the wallhole and not from the window unit?
Maybe something change about that in AC 19?
