Drawing Views 2

An elementary question:
Can you repeat the same view on different drawing sheets?
For example a plan view on sheet one, and a duplicate plan view on sheet 2 (for additional dimensions).
In the past I've always used view arrows to associate views between sheets, but I've never come across any standard forbidding you to just repeat the same view on another sheet?

Stupid question: if you can fit two identical views on your drawing, why not to make bigger view? You know, to fit more dimensions?
 
I have used duplicate named views, but try to avoid them using projections instead (with "section" cutting plane lines). I don't think there is anything in the standards prohibiting this, as long as view orientation is clear.

Typically one is discouraged from repeating view names. One or two sheets, it doesn't seem as if it would cause a problem, but by the time 20 or 30 sheets are there, keeping track of exactly which View G you are refering to can be difficult. I suspect the rule not to duplicate views on a drawing is in ASME Y14.3, Orthographic and Pictorial Views. It may or may not apply to your usage.

Just have multiple callouts and uniquely identify the views and all will be right with the world.

If you want to take true pity on drawing readers, include a sheet function block if there is some other reasoning, e.g. flooring on sheet 2, plumbing on sheet 3, electrical or whatever on sheet 4.
 
Don't complicate more for the machinist, or assembler.
I agree with CheckerHater, make the view bigger to incorporate all dimensions needed.
Adding another view may mean there is another feature like it somewhere, bringing up questions why the view exists.

The question was not for an alternative practice (larger view).
I'm updating someone's drawing who has the same view on 2 sheets and don't feel like doing a major re-draw if not necessary. If anyone knows of a chapter & verse to an AMSE spec, I would appreciate it. Otherwise I agree it is poor drafting practice. Thanks to those with thoughtful responses.
 
I don’t even think it is explicitly forbidden somewhere, but my whole life I used this for rule of thumb: if you have to create two absolutely identical views, you are doing something wrong.
Given all the options, detail views, sections, etc., etc., given how easy it is to create them in CAD, two views indicate nothing but sloppy design work.
Nevertheless, if you have no other choice (working with drawing already created by the company using explicitly letter-size format), follow the advice of evh and 3DDave: give second view explicit identification. If necessary, add verbal note like “FOR CUT-OUT OUTLINE SEE VIEW “Z” SHT.3”.
Good luck!
 
ray98, not sure it's as explicitly clear as you might like but my paraphrasing of ASME Y14.3-2003 section 1.7 especially 1.7.2 would be that if it's not a directly projected view on the same sheet then indeed it should be treated as a 'removed view' and viewing indicators and corresponding view label should be used.

We do it all the time, with no problems. Why does it have to be a stupid question? What if he can't make the view bigger? Should he have a bunch of dimensions no one can read or figure out? Alternatively, should he just leave dims off the print and rely on the machinist to figure out, since that seems to be the norm around here.

ray98,

I don't know what the rule is, but I have repeated views on occasion. Usually, I have an ultra-complicated drawing. I use one view to document one set of features, and the other view to document another set of features.

Multiple copies of the same view are a bad idea on a drafting board or in AutoCAD, but most of us are on some form of 3D parametric CAD. The views will be automatically kept identical.

The views may be kept identical but occasionally it can still be confusing what it's a view of. That's where treating it as a removed view comes in.

Yes, I have often seen situations where one instance of a view is not sufficient to capture all of the detail of a part. The drawing would quickly become too cluttered and difficult to read.
But how to handle duplicates of a removed view? One method would be to have more than one letter designating the view "name", placed so that they would not be construed as a name with double letters (i.e. "AB"). Or you could note "(DUPLICATE)" at each duplicate view. The main thing is to be clear where the view was taken from and that it is oriented correctly.

"TOP VIEW"

"TOP VIEW -- 4-40UNC HOLES"

"TOP VIEW -- #10 CBORES"

All the view names really have to be is unique. You could name them after somebody's cats, but a little intelligence makes the drawing easier to read.

Good solution.

yes, something like this is good. It goes along with my "blithering idiot rule" which (along with standards) posits that an idiot should be able to understand the drawing :)
 
Perhaps one issue is people aren't familiar with the term 'removed views' or how Y14.3 defines them - my CAD package terms them "Auxiliary views" if that helps clarify what I'm talking about.

I think it is bad practice to repeat views. That said, I've done it before with large weldments. One view showed dimensions, the duplicate view showed all the weld callouts, and we named it "VIEW SHOWING WELDS". Just helps to unclutter things.
