General

Bills of material give the designer the opportunity, in addition to the construction drawings with the geometrically represented components, to record all the necessary non-graphic information and to forward it to the relevant authorities.
The most distinctive of this non-graphic information is:

  • Position number
  • Component designation
  • Numbers of items
  • Materials
  • Raw dimensions
  • Component weight
  • Reference to standards
  • Item number
  • Special manufacturing processes
  • Suppliers, etc.
