The application discloses a kind of CAD drawing multi-format BOM intelligent extraction method and
system, method includes: cross-space full quantity lossless analysis;The model space and all
layout space of drawing are cross-space full quantity lossless analysis, directly read drawing bottom entity information;Entity information includes text, straight line, block, attribute and table entity;
Dynamic loading external identification rule;Five-level progressive BOM priority identification strategy is executed, and according to standard to non-standard is identified gradually, and the next level is identified successfully, and BOM data is obtained;BOM data is cleaned;After cleaning, BOM data follows Office Open
XML standard and independently constructs document structure, in the environment without CAD, without Office
software dependence, generates standard Excel format
bill of materials.The application has the advantages of identification
full coverage, offline light weight, rule configurable, cross-space no omission, deployment convenient,
data security and the like.
