Document Control Released Drawing Turn-In & The Archive Process
DCG CHECKS ME10_holding directory
  • turned in drawing(s) not in holding directory will be "REJECTED"
  • turned in drawing(s) without typed in signatures will be "REJECTED"
DCG DRAWING QC PROCESS
  • Discrepancy: basic changes may be made by hand i.e. transposed number, correct revision etc.
  • Discrepancy: technical content changes must be made by generating an ECO or a new revision level
  • Designer must initial and date all hand changes
  • Initialed/dated hand change confirms that the Designer has changed the electronic drawing file
  • Designer notifies DCG that hand changes have been corrected to the electronic drawing file
DCG RE-CHECKS ME10_holding directory
  • if electronic drawing changes have not been made, those turn-in drawing(s) will be "REJECTED"
  • DCG moves checked/confirmed electronic drawing file(s) to archive directory
  • DCG deletes ME10_holding directory file & completes drawing log-in process
