The invention provides a PDM
system digital-analog object automatic creation method and
system based on part number driving, and relates to the technical field of automobile
data processing, and the method comprises the steps: determining a part needing digital-analog creation, submitting a digital-analog creation application, automatically distributing a part number by a BOM
system, and creating a part main data attribute; the BOM system sends a creation request to the PDM system, the PDM system calls a digital-analog
encoder after receiving the creation request of the BOM system, the digital-analog
encoder automatically allocates a digital-analog number according to a part number and a part main data attribute transmitted by the BOM system, and the digital-analog number and the attribute are returned to an attribute field of a part main data object of the BOM system through an interface of the BOM system and the PDM system; and the PDM system calls the digital-analog
template library, automatically matches the corresponding digital-analog and drawing templates according to the digital-analog numbers and the part main data attributes transmitted by the BOM system, and creates complete digital-analog numbers and
data set objects according to the called digital-analog and drawing templates.
