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.
