Drawing numbers and part numbers
Drawing numbers and part numbers
(OP)
I hope I've submitted this in the right place - seems the most relevant...
I have a simple sounding question - is there a preferred system for numbering drawings and/or parts?
I have in the past used a system where the part number gave information about what the part itself was, another system where the part number gave information about which product it was used on, and another system that gave no information whatsoever and was just a sequential numbering system.
I work for a company that is fairly new, and trying to come up a consistent system that is, if possible, approved or recommended by ISO or other bodies.
Any comments would be welcome!

RE: Drawing numbers and part numbers
In a nutshell, dumb numbers are usually best, semi-significant are also good, but avoid complex, boxcar numbers where every digit has it's own meaning.
I don't think ISO cares what numbering system you use, just that you follow one that is documented.
Anyway, check that forum out. There are threads there addressing this very issue.

In summary, current thinking seems to be that dumb numbering is best. Other information like used on etc. can generally be contained in their own fields as meta data in CAD files, ERP systems etc.
