Drafting Standards,BOM Standards, and P/N standards
(OP)
Does anyone have a copy of a "newer" company standard that they can share with me? I've been choosen to write an engineering standard for our company. I've been doing mechanical engineering for 15 years and I've never seen this, except an old one that related to autocad users and layers, line types, ect...we Solidworks. I feel I should just write one sentence "follow ASME standards". However I feel what they are looking for more of, is when and when not to use a BOM for example. We have someone here that puts a bom on every print he does no matter what really. I of course do not. Part numbers are another big one here, there are a lot of parts in our system called "top", not good. Can't open two of them in SW at the same time of course. Everything I know should have it's own unique part number. 99.9% of the stuff we engineer all goes out to a vendor to make as well. If any of you have something to share that would be awesome! I know some companies have a definition of what an "assembly" is....stuff like that maybe.

I swear there were vaguely similar questions before but I'm having trouble finding them.

It isn't just how to make a model or how to do a drawing. You must also consider how to manage your files.

Search for standards for other articles that may help too.

On when to use a 'BOM' (as I've mentioned before parts list is more appropriate terminology) and what is an assembly ASME Y14.24 addresses this to some extent.
So I'd expect just about all 'assembly drawings' to have a parts list (parts list may be a separate document though) including inseparable assemblies.

That's how I've done it. My drafting standard is only 4 pages long, and most of that is talking about location and use of templates.
Something like "Fully define the product on a drawing or in the model using ASME Y14.100 and associated standards."
Also, "Where this procedure differs from ASME standards, this procedure takes precedence."
These aren't the exact words I used, but are the general content.

As for BOMs and file names, I agree with KENAT; any assembly drawing should have a related parts list (including inseparable assys). I have seen companies that would have a parts list on all of their drawings, assembly or not, to capture material information. While many may question the value of a system such as that, it did work for them.

Also, they may have a bunch of stuff that is barely relevant to a lot of places.
Also, while fairly popular, they aren't industry standards so it's pushing it to expect vendors etc. to be familiar with them, though they generally follow the standards.
I still prefer making ASME Y14.100 etc. my primary reference with the other DRMs as at most a back up reference.

Though I've not read Machinery's Handbook cover-to-cover, so far I can truly say I've never encountered any philosophical arguments unduly represented within its pages, unlike Genium's book which actually tries to convince readers to the author's opinion with unsupported argumentative statements. Not very professional and completely out of place in a reference guide. I contacted them about this on one of their articles within the book. I initially received a positive and receptive response from one individual (not one of the authors). However, the changes in their recent update ended up being even more unsupported and argumentative, I suppose in a vain attempt by the author to convince everyone else that he was right. This is how I discovered that they really aren't vetting their book. I now question any purchase of further updates and would rather spend the money to purchase the actual standards directly.
