is there a standard for markups?
i am a design tech and and as such i am in charge of marking up drawings to be revised as well as archiving the markups and revisons etc... we do markups by hand and the revisons are made to the electronic files later. we use solidworks.
my question is; are there standards specifically for markups? we all use clouds, are there other tools i can use to be descriptive that are a markup only device?
on multi part drawings (which we try not to use)where a single part is no longer used i typically draw a cloud around the part and then a rough hatch over the part.
if anyone could point me to an industry standard (if not ansi) i would greatly appreciate it.
thanks.

edrawings professional will do electronic mark-ups.
per a major aerospace company:
yellow marking indicates acceptable.
red marking indicates a deletion.
blue marking indicates an addition.
green marking indicates suggested changes.

the only checking standard that i am familiar with is the one posted by chris.
i've seen the one by chris but with minor difference.
yellow marking indicates acceptable - keep as is.
red marking indicates a change.
blue marking indicates an "checker" comment or question.
green marking indicates "designer/draftsman/engineer" comment or question.
if an entire view is to be deleted then hatching it in the appropriate color is a good way to go.
i'll try and get my checker to post see if he says different.
even chris's color chart is not universal. more common i have found is:
red is for required corrections
yellow is accceptable as is
blue is for non-mandatory suggestions and comments
the three above are usually used by checkers.
green is for comments, additions, corrections, generated by the engineer or designer.
the main answer however, is no i have never seen or heard of a universal mark-up standard.
a lot of companies will add one to their drm manual.
we use solid edge, and it has a "view and markup" fuctionality in its' "revision manager" function, but (sadly) the programmers didn't think to include gd&t symbol capability to it. as i recall, pro-e has a similar mark up function.
and per another large aerospace engine manufacturer, the standard is(or was when i worked there):
yellow marking indicates a deletion.
red marking indicates an addition.
blue marking indicates acceptable.
green marking indicates they ran out of blue.

everything should be designed as simple as possible, but not simpler.
gunman: i have run into people who worked at that place, and when i first gave them a check print with virtually all yellow marks, they came unglued, to put it mildly.
... and a big black "x" means start over!

chris,
or, the wadded up print coming over your cube wall.
