Abstract: With the wide use of paperless production model, the management of numerous
data of engineering drawings and BOM becomes an important research field. A system of
engineering drawings and BOM management based on design environment is introduced. The
system takes whole parts or whole products as dividing units and integrates them directly in CAD
system based on database technology. It avoids the tedious management process of softwares such
as PDM and PLM etc and it is more convenient for designer to use. The system takes engineering
drawings as data bases and can generate BOM reports in several formats. The reliability and
effectiveness of this system is verified in a practical application on enterprises production.

Key words: computer application, BOM management, database, engineering drawings
