Revision and pages
(OP)
Hello Everyone,
I am a new engineering in the field working on some drawings. I have a few questions pertaining to parts on multiple pages and the like.
Little background: In college I took about 4 to 5 classes on drafting, so I know a little but still have a lot to learn.
1) The part I am working where the paper size is limited: is it acceptable to up the part on multiple sheets of paper. Ex: have the front view on page 1, have the back view on page 2?
If number 1) is a no go, then you can just ignore number 2).
2) if it is acceptable to put the part on multiple pages, do you put the revision description on all the pages, or just the one with the change. I do understand that all the pages need to have the rev number updated.
Thanks everyone.

If you are at the largest format you have, add sheet 2, etc.
Each one can have the revision listed same as the first sheet.

You can also put the primary views at a smaller scale on sheet one and then use auxillary views on the other sheets to do the detail dimensioning.

However, with CAD I'd lean towards all sheets being same rev - still showing the rev on all sheets though.
As Ctopher says, my preference is to go to larger sheet first, additional sheets only once you've reached the limit of that approach. However, some folks will disagree for one reason or another such as prevalence of B/A3 limited printers.
EWH makes a good point too, without the reference arrows for removed views it is not always clear what direction the view comes from and I've got lost because of it on other folks drawings.

I strongly believe every sheet should have the same revision level but you do not need to duplicate the revision table, we don't even put it on the drawing. It lives in our ECN's which are now computer searchable. Second & subsequent sheets can have a greatly abbreviated title block which helps conserve space.

I have seen engineering release systems that allowed each drawing sheet to have its own rev level. But like others I prefer all drawing sheets to maintain the same rev level. And I prefer all the change descriptions to be listed on an ECN, with the rev block on the first drawing sheet simply giving the ID number of the ECN(s) associated with the drawing release, and the rev blocks on subsequent sheets saying see sheet 1. Eliminating duplicate data entries on each sheet helps minimize errors. It is also important to explicitly describe every change to a drawing/BOM/effectivity so that those responsible for implementing the change understand what is involved. There is often not sufficient room in the drawing rev block to adequately describe changes, so it is better to use an ECN form.

Technically it is regulated by ASME Y14.35, "Revision of Engineering Drawings and Associated Documents".

7.5 of the same standard deals with adding sheets.
BraunP I suggest you take a look, discuss with your boss/colleagues and come to your own conclusion.
