Drawing Numbering

[czc]

There is something about my companies drawing numbering that bugs me.

 

It goes project number - area number - sheet size - discipline - sequential number

 

What bothers me is including the sheet size as part of the drawing number. There is space on the title block for the sheet size (A1, A3) so it just seems like duplicating information. Is this some left over from Paper Drawing filing systems. Does anyone else include the sheet size as part of their drawing number?

There are manufacturing companies that routinely incorporate sheet size as part of their drawing number. However, judging by the ones I have seen most do not duplicate the information in the title block area.

never seen sheet size in drawing number, seems a waste of effort.

 

we use:

project number - discipline code - sequential number.......

 

i worked in a few different engineering companies and this pretty usual.....

Every company has its own way of doing things. Have you ever done manual drafting?

Yep its a hangover from the manual draughting days.

 

0A123456

0A123457

1A123458

3A123459

2A123460

etc...

etc...

 

People used to file hand drawn prints in big cabinets and the first number gave the size of the cabinet where you looked for the drawing.

Of course nowadays (nearly) all drawings are done on cad and computer sorting routines put all 0A's first, then 1A's, 2A's, etc. which is not what you want from a database point of view.

Thank you NukeCAD. I recall those days as well (thus my question re: manual drafting). The letter "D" was for Dinosaur size drawings! LoL

When we get a drawing request I assign it a four digit number (i.e. 2708 ). Also, we have a three digit code for each of our customers (i.e. 909). We take both of those numbers and combine it with a two digit number for the year it was created in to make our drawing numbers. Using the examples shown, the drawing number would be 13-909-2708.

 

Since we are a manufacturer, the four digit number is also used to create our part numbers for use in SolidWorks. Part numbers are seven digits long and the last three digits are separated from the first four by a period (i.e. 2708.001). The fifth digit in the part number lets us know whether it is a sheet part (plywood, MDF, particle board), solid wood blocking, steel or aluminum, or any other materials that we typically use. There aren't a lot of parts that are used between jobs, unless they are purchased, so each job get its own set of part numbers. This makes it real easy to store things in the vault and not have parts be accidentally overwritten.

SuperCAD, just remember:

 

Someone, somewhere in your company has probably broken the foolproof and overwritten something, as is the way with Sods law. (Also known as Murphy's law)

That's the beauty of having a vault. They CAN'T overwrite it unless I authorize it.
