Drawoh,
Thanks. I like that you say you use revision symbols for cases when it's not obvious where the change occurred. I think that's the key here. When you want to draw the reader's attention to a particular location in the drawing or document, and it's not obvious, then a revision symbol...
dgallup, thanks. That seems reasonable. The only minor drawbacks I see to doing that is that it adds clutter to the sheet, and the info provided by the revision symbol is redundant with the description in the revision history block.
In the end, I think the goal of notation should be to make...
Hi mtkenney,
Thanks for the info! What you say is consistent with the recommendations in ASME Y14.35M-1997, Revision of Engineering Drawings and Associated Documents:
"7.5.1 Adding Sheets. Added sheets constitute a change to the drawing and shall be explained in the Revisions History block...
Hi dgallup,
Thanks for your post. It's good to hear an argument for a revision symbol, just to move toward a balanced view of the pros and cons.

Hi 3DDave,
Thanks; your suggestion to forego the revision symbol sounds reasonable. We don't currently have a standard regarding this case, so we have the freedom to define how to handle this situation. I'll recommend that we not use the revision symbol, unless someone convinces me otherwise.
Hi drawoh,
Thanks for your reply. Yes, adding a note in the revision block is one way of letting people know about the change. But what about the revision symbol in addition to the note? Are there any standards that say anything about revision symbols when adding a new page?
Hello,
What are the typical ways of placing a revision symbol when an ECN requires a new page? For example, suppose you have an engineering drawing that only has one page. Then you need to make a change to the drawing, but your change won't fit on the existing page, so you need to create a new...
