dimensioning to hidden lines
the question of whether to dimension to hidden lines came up a few weeks back and i think the reference given was slightly wrong.
asme y14.5m-1994 paragraph 1.4g (not 1.4c)
[quote] ... dimensions should be shown in true profile views and refer to visible outlines. [\quote]
my checker and i were looking for it this morning.

(sorry user error)
asme y14.5 para 1.4(g)
if the original post refered to para 1.4(c), then you are correct, it was a typo.
ewh, it wasn't a dig.  your original post pointed us in the right direction, just thought i'd post the paragraph in case anyone was looking.
my checker just got a drawing from another division of the company to look at which leaves a little to be desired, this is just one of the issues.  being from another division he was being extra cautious and making sure he could back up any changes from the standard.
no problem!  this is a prime example of why we should use this forum as a resource, but not as a final authority.
a pretty fundamental rule: don't dimension to hidden lines.

kenat,
   the standard says "should" as opposed to "shall".  sometimes, i hate adding a section view to an otherwise, simple, easily read drawing.  
   okay, i am being pedantic.

hey, i'm just quoting the standard, i'm making no judgment.
ok that鈥檚 a lie i do have an opinion but it鈥檚 my opinion not a rule, unless one day they鈥檙e dumb enough to make me a checker鈥︹
