Daniel,
This "atrium door", is it like what some US manufacturers
call a "patio door" , meaning one leaf is hinged off of the
side stile of the other leaf ?
If so, I have one you are welcome too.
Be advised, it does not implement all the
turn-down menus in the settings dialogue of
doors and windows in AC 8.1 and later.
It does have the necessary parameters in a list,
which is how I prefer it.
PM me with your e-mail address if interested.
Peter Devlin
