Note sequence in drawing 1

Does the Notes from the drawing have a sequence?
Meaning that the note is practice by note 1 than to note 2, note 3, etc (or a, b, c...)? Or it doesn't matter?

For what it's worth...

From Y14.400-2013 (empasis mine):

4.27.6 Drawing Notes — Contents. Drawing notes are pertinent data given in word form and used to complement
the delineation of other given data. Drawing notes shall be concise, grammatically correct statements. The arrangement
of the notes shall not be interpreted as an order of precedence, or sequence in manufacturing or assembly,
unless specified as such on the drawing.

To ewh, can you provie a snap shot for this statement?
Thanks!
 
Sorry, I mis-typed... the relevant standard is Y14.100-2013.
That was a cut and paste directly from the standard. It continues with paragraphs regarding Language, Language Style, Commonly Used Words and Phrases, etc.
I am unable to scan it at the moment, so if you want better you will need to find a copy.

no problem because I tried to find Y14.400-2013 and no clue at all.
 
If the document is a CAD-generated Work Instruction or other process document then there can be a sequence. The document would need to make clear that the notes are to be followed sequentially.

Also, just because the notes don't have to be sequential doesn't mean being arranged generally sequentially doesn't make them easier to follow.

I'd suggest best practice might be to have generally sequential notes but if a subsequent revision or some such messes up the sequence then you don't need to worry about it.

It's key to remember that during drawing revision (after being released), if a note is deleted then the number is not reused but kept in order to retain the original numbering of the notes. If, say, Note 6 is deleted from the drawing then it would look like: "6. DELETED.".


Tunalover
 
That's kind of the point I was making tuna. The origins of the text in Y14.100 may be in part a hangover from hard copy drawings and the rules about not reusing note numbers etc.

You are correct about sequence, tunalover, and that is covered in the last part of the exerpt "...unless specified as such on the drawing."
I too try to put the notes in a logical order on new drawings.
As for not repurposing a deleted note, it may also be because the note in question may be referenced in other documentation, and a larger screw-up could occur if the note was repurposed than simply deleted.
Similar situations can occur in parts lists.

Seriously, I strikeout the note instead of using the word-->"6. DELETED."
I need to improve this.
 
I think strike out is still valid, I forget which spec might clarify this perhaps 14.100 or 14.35 - if it's even mentioned.

I totally distrust any procedure that requires me to trust the end user's font. Your crossed out note probably will not survive translation to another CAD[ ]format. If you need to keep the note number, I strongly prefer the text "DELETED".

If someone needs to know what the original text said, they can look it up in your PDM system. If the note is no longer valid, production does not need to know about it.

Doesn't necessarily require you to trust the end users font. Could be an actual geometry line strike through.

KENAT,

A geometry strike-out line only works if the font does not resize, and the text does not move.
