as far as i know the rest of the continent is in metrics and uses neufert. at least here in ecuador we do. but i got an ags when i was a student, and have been using both ever since. i'll use ags when i need/want a specific, standard dimension, and neufert perhaps more for architectural configurations and specific dimensions of objects [well, like you said]. i think also ags has more construction details than neufert [this off the top of my head]...
but i thought i was going to see a photo of both books menacingly staring at each other. bah.
for some data you really weren't asking for, ernst neufert studied in the weimar bauhaus and worked with walter gropius. i say this because i was always fascinated by the fact that he was an actual person [in contrast to the more anonymous ags]. there's a photo of him in the leaflet of my neufert, this little old man with a toothy smile and a bow tie.
anyone have the neufert discs where you can plug in your height and all the corresponding dims for tables, chairs, etc are revealed?
but yeah, i'm more partial to neufert but try to pay attention to the AGS for detailing cos i'm not so good at it.
