Title Block Question 1

[kislyak]

Need your help.
We have a dispute with our local drawing checkers. They claim that if an area in a title block is intended to be blank then per the national standards you MUST have a horizontal line in lieu of text. In this example it’s a project number, and for this particular drawing project number does not apply.
Does anyone know where in our national standards it talks about that? I did look at ASME Y14.1 Section 6 where it talks about title blocks and did not find that info there.
Any ideas?

From what I remember, it's DOD-STD-100C.

If no information is applicable enter a "dash" or "N/A"

Thanks but the DOD-STD-100C is canceled and replaced with 4 documents:
ASME Y14.100
ASME Y14.24
ASME Y14.35M
ASME Y14.34M

Does anyone know the exact place where it says that?

Have you checked the appendices of 14.100?

Yes I looked at appendices of 14.100 and did not find it. I know it days it can not be black. But I can not find where it says to put N/A or dash "-".
Anyone else know where to look?

 

[kislyak]

Sorry my spelling is bad today! Here is what I am saying.
I know it days it can not be black. = I know it says it cannot be blank.

 

[kislyak]

I still can not find where it says to put N/A or dash "-".
Anyone?

Any drawing checkers out there? Please help me find where in the standard it says to put a "dash" or "N/A" for items that are not applicable in the title block. I do remember from school 12 years ago something about that too. I just need to find where it says that in the standard and so far I am having a hard time finding that info in the national standards.

I'll say this. Per the 1998 edition of Y14.38 most "/" were removed from most abbreviations.

So 'Not Applicable' is in fact "NA" with no slash.

This happens to be the same abbreviation as for "Not Available" and "Next Assembly".

So, I'd use this as justification to use "-" instead of an abbreviation with multiple interpretations.

As someone who got to be a checker for a couple of years, this seems a fairly trivial item to be putting so much effort into - or am I missing something?

I agree with Kenat's suggestion to use a dash ( - ). I never had a problem with the FDA or FAA when my designs had that much scrutiny. In your internal drafting policies, you could define the dash and just ensure that you use it consistently, in my opinion.

I don't know of any standard but we usually put -- or ---- in any blank field just to show you didn't forget to fill it in. Bigger fields get more dashes.

In the UK we put a diagonal line, or 2 lines like a saltire, in blank boxes.

However, the OP didn't bring that one up and I don't want to get his checkers going;-).

OK, Ken, I have to admit that I needed to look up "saltire."

Thank you all for your input. I agree that a – (dash) or - - - - - (multiple dashes) should be acceptable per national standards. But for some strange reason our checkers (just 2 of 10) are requiring to have a long solid line and not a – or - - - - - -. One could argue and say that - - - - - is a line, it is just that it happens to have a hidden line type/style to the line. But - - - - - appears to be not acceptable for our 2 checkers, they require a solid line. I believe this requirement to have a solid line is not a national standard, just something they want. And that was the essence of my question.
Thank you all for your help.

(Belanger, I had to look it up too, I wasn thinking St Andrews cross but had to double check it was the right one and in the process discovered that technically it's a saltire).

I think a dash line or a solid line is nit-picking, either way it gets the point across. A short solid line is acceptable.

kislyak, there is no arguing with your checkers if they proceed from title block is space for drawing lines instead typing letters.

 

[MadMango]

If your Checkers are demanding a solid line, have THEM provide the reference. In my experience, either "NA" or a single "-" have been used.

Have you read faq731-376 to make the best use of these Forums?

 

[dgallup]

The reason we use dashes is that these fields are automatically filled in by model parameters which have to be text strings of some sort. A solid line is not an option.
