duplicate views
duplicate views
i have a part that i am attempting to dimension that has so many features that it is very difficult to fit them all on one view. is it appropriate to use a duplicate view on a second sheet and split up the dimensioning? my idea was to dimension the profile on page one and locate holes on page two.
thanks.
check out our whitepaper library.
you need to make as many views and pages possible to clarify what you want. obviously don't make 100 views and pages.
i don't see a problem making a duplicate view, but make it clear what it is.

there is as far as i know no problem in having a 'repeated' view and is something we do on occasion.
however i believe the 'second' identical view should be shown as a removed view. that is as 'view a-a' or similar, fig 9 of asme y14.3-2003 is an example.
chris, while i think i get the intent of your first sentance i think a slight change of wording might be in order, i'd suggest:

kenat,
i agree with kenat, make the second view a removed view so that it avoids confusion. the second view will not be orthographic so it will have to be identified with a view label.

gmurray79,
i have had your exact problem, and i solved it with a duplicate view. this is dangerous practise on a drafting board or in 2d cad, but it is perfectly safe in 3d, where the view is controlled by the model.
as noted above, make sure you label your views clearly.

what you are ding is what i have done in the past, holes tend to be a different oprastion then machining and keeping the holes on one view will help. i would keep the same starting point for the dimensions or have a datum will help. putting ref dimensions will also help.

i second kenat's motion of keeping the pages to only what is necessary. i've seen 8 page drawings that only needed to be 3 but the engineers opinion was that he wanted to make detail views take up half the c sheet when there were only 4 or 5 dimensions to show and anyone with halway decent vision could have clearly read the dimensions out at half or 1/4 that size.

to reinforce what motorvib says - the dimensioning schemes on both views should normally come from the same origins, preferably datums.
we have had problems with people swapping origins when they have multiple same views leading to tolerance issues.
occasionally, we have very small complex parts that end up with 3 views. in this case we'll have 2 identical removed views, we've treated them both as 'view a-a' since they are projected from the same orientation, however i'm not totally sure this is correct. it just seems silly to have identical removed views with different letters - i suppose the disadvantage is if you want to distinguish the 2 views.
kenat,
gmurray79,
this is a good application for a hole table. if you have a lot of holes, this pulls their dimensions off the main drawing view.
