question on the drawng number in PDM

Absolutely.

Sometimes later versions are created to correct a problem. Other times different versions are designed for a specific application. In any case the version is very important. The end user should always be aware and use the proper version. In the PDM it would be ideal to have a separate field for the version number and date. If it is not possible, it can always be added in the comments or remarks field.

Use numbers like this 108965A where 108965 is the P/N and A is the version. It's easy to separate the fields when you want.

before we used suffix letter such as "a","b",and so on to the drawing number. later we found the suffix letter didn't work as a version number but a part of drawing number.

would somebody give me a web artitle about the PDM drawing number. THANKS

We use the Sage system for Bills of Materials etc. & our ID number takes the form of 'drawing No./issue No.' so we might have a drawing 1234/2 which would be superseded by 1234/3. We can also have part variants which might be 1234A/2 etc.

This seems to work OK although we made the mistake of adding the drawing sheet size as a prefix which just adds to the amount of typing needed.

Yes, I'm doing some contract work for a US-Asian company that does that. They appear to now have perhaps 15 or 16 prefixes in use and get lots of confusion since they repeat the rest of the number. Bad idea.

could you introduce an advanced and reasonable drawing ID method?

in my company, except the drawing number with issued no., a part number is added to the part, and the part number would be used in procurement,storehouse,and machine process. what a sily action! I am very very angry at the complicated number system. but it is a pity that i can not give a reasonable number system .

My experience with drawing numbering systems has always been that the more information that I try to incorporate into a number system, the more ridiculous and unwielding it becomes so through the years, I've adopted the KISS principle - Keep it Simple, perhaps incorporating a portion of the drawing number that reflects a customer or portion of a system and everything else is simply sequentially assigned. The purpose of the PDM system is to ensure that the user utilizes the appropriate revision of a component and that will be managed through the appropriate information being included in the Bill of Materials.
