Numbering and Revising Multisheet Drawings Question
Numbering and Revising Multisheet Drawings Question
(OP)
There is a difference of opinion in our company regarding the numbering and revising of multisheet drawings. The current company standard is to put Sheet 1 of X on the first sheet and then number the following sheets as Sheet 2, Sheet 3, etc. If one or more sheets of a multisheet drawing are revised, only the revised sheets are "reved up", not all sheets.
Our company acquired an electronic controls manufacturer who wants the drawings to have the Sheet X of X on every sheet and when any sheet within the multisheet drawing is revised, they want all sheets to be "reved up" to the same rev level which they say is an "industry standard".
Does anyone have some input on this? My background is mechanical and I am not familiar with the electronic controls industry.

RE: Numbering and Revising Multisheet Drawings Question
I have seen revisions done both ways, though very rarely see separate revisions on drawing sheets. A drawing is usually considered "one" item, with every sheet reflecting the revision level of the entirety. This is also often driven by the CAD package and PLM (if any) systems used.
As to the "SH X of X" on every sheet issue, I have also seen that done both ways. If memory serves, it was DOD-STD-100 that drove having the total only on the first sheet method, but I rarely see it used today.

RE: Numbering and Revising Multisheet Drawings Question
Both of our clients use the following:
Sheet 1 has "SHEET 1 OF X" where "X" is the number of sheets. There is a block on the sheet with all the sheet numbers and their revisions shown (called "REVISION STATUS OF SHEETS"). Sheet 1 allways gets revised if only to state "REV STATUS OF SHEET 2 AND 4 CHANGED".
All other sheets just state their sheet number. They are revised only if there is a change to that sheet.
Your practice is probably similar.

Now, about those sheet numbers...

How well some CAD/PDM/ERP or similar systems can manage this is another matter.

Note the "an" ... not "the". It is one of several 'industry standards'.

RE: Numbering and Revising Multisheet Drawings Question
We put sheet N of X on every sheet and all sheets have one rev level. That way, if you only have one sheet you can find the complete drawing package.
The other way may be acceptable, it doesn't make it smart.
RE: Numbering and Revising Multisheet Drawings Question
Nothing hopelessly complicated about it in the right application.
Like wise only having sheet no. and not sheet "x of y" also makes a lot of sense for hard copy drawings.
(Oh, and before you make a smart comment about the UK still being on hard-copy - so were many of the American drawings I dealt with in that job.)

RE: Numbering and Revising Multisheet Drawings Question
In the case where all sheets of a drawing are kept at the same revision number/letter, does the revision note get written out completely on all the drawings?
Say I have a drawing consisting of 4 sheets, and in one view on sheet 2 somebody typed in a dimension incorrectly. So on sheet 2 I put a revision stating "Dimension was 3.155, now 3.511" or something. Would I put that same revision note on pages 1, 3, and 4? Or on those sheets, would I just update the number without any indication of what was changed? Or on the non-affected sheets, would I make the revision note say "Revision to sheet 2".
In some programs where all the sheets are tied to a single file, it may be easiest to have all the sheets have the complete revision note in the title block. However, we are using AutoCad, so each sheet is a different file and the updates need to occur independently.
Another thought, maybe I'm wrong altogether here... Do people normally have a "revision table" with the note explaining what was revised on EVERY sheet, or is a different sheet format used that only has the location for revision notes on the top sheet? I think that would probably make the most sense if all sheets in the drawing are kept at the same revision number/letter.
Anybody care to clarify how they do or have seen this method applied?

We would but "No Change on this Sheet" on sheet that did not chnage.
Another note we used was "Sheet added at this rev".

They only have a rev history block on the 'sheet 1' format, the continuation sheets don't have a rev history block, just the current rev.
This is in a system that has all sheets at the same rev.
I think the UK system I worked had the same format for all sheets with rev history on all sheets BUT only teh ECO # was given, no details.

RE: Numbering and Revising Multisheet Drawings Question
So, I'll add my 2 cents as follows:
It makes logical sense to have "Sheet X of Y" on each sheet, that way you can tell which sheet came from where when you're working on a large desk and everything gets all jumbled up for some reason.
Revision control is done on Sheet 1 of Y. You can link a "rev cell" on each subsequent sheet to the main rev on sheet 1, and it'll take care of all of it. I do agree that controlling the revision level of all sheets separately is too cumbersome to be practical.
Also, typically in my multi-sheet prints, I'm referencing some kind of large assembly or complicated part with many views. In either case, the title block should be reflecting the same part number across each sheet... so, revision control in then intuitively common. If you change a part on sheet 3, it'll affect sheet 1 since that's the main view of your part / assembly. The revision block on sheet one should say "changed widget, sheet 3" and there you go.
Maybe that's my method and it doesn't make sense for others... but, that's how I handle multi-sheet prints and rev control of them.

A lot of the 'old conventions' were to minimize changes on hard drawings.
