all over or all around?
"all over", yes, i said "all over", not "all around". i was just wondering if it made it into the final release of 2009.

yes the all over did make it to the 2009 edition.

dave d.
yes, all over is one of the five new symbols in 2009 standard, it means the profile of the surface tolerance zone applies in all views simultaneously; this controls size, angle and location of surfaces
seasonlee
yes.
3.3.25 all-over symbol
this symbol indicates that a profile tolerance or other specification shall apply all over the three-dimensional profile of a part. see figs. 3-11, 3-20, and 8-8 and para. 8.3.1.6.
the note: "all over" may also be used in place of the symbol.
it's funny, the wording for the definition of the symbol does not limit it to profile of a surface, thought it is clear this is the main intended use. the authors left it open to use the symbol in other cases.

fcsuper:
those words "or other specification" in 3.3.25 of y14.5-2009 will cause questions, controversy, and disagreements for years, until the next revision. just like the deletion of the word "profile" did in para 3.3.18 of y14.5m 1994 did for the "all around" symbol.
my buddy kenat: can you get that place you work at to buy you a new 2009 version of the standard?
checkron,
so you will go bonkers if you see one of your guys try to apply an all over symbol to a fillet radius callout?

you must be joking ron.
i might be able to but it's not a fight i fancey. i let jon fight those fights, with his departure my main plan is to keep my head down. i plan on maintaining my own integrity but i'm not going to force it on others as i'll have no back up if they don't agree. i'll let manufacturing fight the good fight for the most part, i tried working with them on it a little but it wasn't easy.
kenat,
i hear and understand, ken. persevere!
all over symbol on a fillet radius?! that's cute, but somebody will probably try it.
