View labeling on multi sheet drawing
View labeling on multi sheet drawing
(OP)
Is there a section of any ASME specification that talks about how views on multi sheet drawings should be labeled? I am not referring to cross referencing for things like sections or details, but on complicated drawings where the views may be repeated on subsequent sheets with different features dimensioned. (For example, a machined electronic enclosure where sheet 1 may have the box dimensions, and sheet 2 may contain similar views but dimension the holes). Does there need to be some sort of cross reference to the views? Maybe one view labeled "top" on all sheets, or some other relating verbiage?
Thank you,
Thank you,

If we need to reference the same detail more than once, we always add a descriptor under the label so that the reader can easily understand that, while it may be a redundant view, the information shown is not. If it is a redundant projected view, a definition hinge line is added to provide identification and only the additional projection is labelled (since it would be in effect a "removed view").Ideally each view not in direct projection should have a unique identifyer.

I guess it all comes down to doing whatever is clear and understandable to the end user. If the view is distinct enough that it would not be confused with another, an identifier may not be needed, bit if it could be confused with another view... ID it. It appears how this identification is to be done, is not defined, so that leave it open to whatever each company wants to do.
Thank you,

If in conversation or on a quality report or somewhere you need to be able to distinguish then use the zone & if applicable sheet number to achieve this.

Kenat. I have used what you are referring to also in the past. Unfortunately it appears to not be allowed per the ASME requirements, so I will have to stay clear of that method. Per ASME Y14.3 Section 6.5 Cross-Referencing Views "View identification letters shall not be repeated on more than one view. Only one set of alpha characters shall be
used per drawing for naming views of all types without repeating the same letters on more than one view. For example, for a drawing consisting of three named views
of either the same or different types (a section view, a removed view, and a detail view) the views would be named SECTION A-A, VIEW B-B, and DETAIL C."
Thanks.

Now, since everything is printed at B size or smaller, related views must be on a different sheet, and I'd do every damn thing possible to help the reader navigate the mess, regardless of what any standard defines as minimal.

Having all the views laid out on a single sheet is SO much easier to read the drawing - even on the computer screen to me.
If users want to cheap out and not have a plotter they can also get magnifying glasses for all drawing users.
