    Drawing numbers for parts that have multiple drawings

    Terry Raymond

      We're getting new drawing and part numbering methods with EPDM implementation.

       

      We are mostly project based and thus are constantly making new parts, each which gets a part number.  Most parts will only get one manufacturing drawing.

      Some parts will get other drawings (machining, installation, GA, interface, etc).  Some drawings are made where there is no part (ie autocad dwgs).

       

      I see these options for drawing numbers:

      1. Dumb serial numbers (no link between part number and drawing number). - I like this simplicity, but seems like it may be hard to find the right drawing.  Ie if a BOM calls out part 129348, how do I know to go get drawing D101391?
      2. Drawing number (dwg filename) matches Part number (model filename) for most parts.  This seems to be what Solidworks likes the best... Some other number for special drawings for parts.  Something else for no part drawings.
      3. Manually append a suffix to the part number.  Drawing number = "<partnumber>-D<X>".  Something else for no-part drawings.  This is similar to our current method.

       

      Which method do yall see causing the least problems? 

       

      I know this type of question has been asked a thousand times.. couldn't find this one specifically. 

       

      Thanks for insight!

          Terry,

           

          We use a version of your #3 choice. This at least maintains a commonality between the part/assembly and the associated drawings. The commonality is convenient when sorting and grouping - similar file names appear together.

           

          Not sure this method is best / better than others but works for us. It does require a standardized set of suffixes.

            Before EPDM, most places would use an Excel Spreadsheet, an Access database, or a proper database (e.g. ERP). Using just EPDM, the software actually maintains the link, so you can click "Contains" or "Where Used" to find out what is used where. You can also have Part Number/Drawing Number as part of the data card which you can display in the details column. It's not difficult, but you are correct that it isn't as immediately obvious.

            Drawing number (dwg filename) matches Part number (model filename) for most parts.  This seems to be what Solidworks likes the best... Some other number for special drawings for parts.  Something else for no part drawings.

            Manually append a suffix to the part number.  Drawing number = "<partnumber>-D<X>".  Something else for no-part drawings.  This is similar to our current method.

            The problem with the final two solutions is that immediately you create edge cases where the rule does not apply. These "grey areas" are where things go wrong. People often have their own interpretation as to best practices so you get a hodge-podge of personalised "conventions".

             

            We use solution #1

              #3 gets my vote!

              Model and Drawing have the same name, and any iteration of those gets a Derived/Child number or suffix

               

              P12345-00.sldasm

              P12345-00.slddrw

              Derived Drawing would be

              P12345-01

              P12345-02

              P12345-03...
