Manualnumbering VS Autonumbering
Hello,
before 6 months we started Windchill 10.2 implemetation. After some time l have some basic problems with parts numbering. Will describe my situation and problems.
Present situation:
- before Windchill we had use following file name schema:

- each part and assembly includes "extract" function in relation ---> project number and drawing number is included in file name
- 00_00_00 ---> is some logical "model tree" schema ---> example: subassy 01_01_00 includes parts 01_01_01, 01_01_02 ...
- in praxis it means:
assembly moved in model tree ---> rename parts and drawings
- l want keep this logic inside Windchill
Problem:
- during first stage of planing we are changing product structure (model tree) quite often
- Windchill is quite sensitive to rename from the reason of "Drawing - 15009_v01-05_02_05_00.drw is not unique."
- SAVE AS copies does same problem sometimes
My ideas and solution:
- Do l need model number? ---> NO, because all informations are included in file name
- ignore model number ---> turn it to AUTONUMBERING
- will Autonumbering help me? Model number is only for Windchill internal functions, but l´m interested only in file name.
My unskilled imagine about autonumbering:
- Windchill will change model numbers automaticly ---> it will never occur "Drawing - xx_yy_zz.drw is not unique" or am l looking thrue pink glasses? 
Thx for any help or tips...
