Method and apparatus for automatically generating budget table of engineering drawing

Abstract

The invention discloses a method and an apparatus for automatically generating a budget table of an engineering drawing. The method comprises the steps of 1) creating a graphic block object simultaneously containing a graphic element symbol and text attribute information of the graphic element symbol for each graphic element symbol required to be subjected to information extraction in a design process of the engineering drawing, and inserting the graphic block object into the engineering drawing; 2) selecting or creating an information extraction system, automatically extracting the text attribute information from the engineering drawing to generate a material bill table, and sending the material bill table to an e-commerce platform product recommendation system; 3) automatically retrieving and matching all brand manufacturer lists meeting the requirements by the e-commerce platform product recommendation system according to specification requirements of device materials recorded in the material bill table, and selecting corresponding manufacturer brands for devices from the brand manufacturer lists; and 4) performing automatic calculation by the e-commerce platform product recommendation system according to the unit price and quantity of selected manufacturer brand products to generate the budget table of the engineering drawing. According to the method and apparatus, the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of information processing of engineering drawings, and relates to a method for automatically extracting text attributes of graphic elements in engineering drawings, and in particular to a method and a device for automatically synchronously generating material lists in engineering drawings for intelligent statistical analysis and engineering budget estimates. Background technique [0002] With the rapid development of computer software and hardware, computers are widely used in engineering design, machinery manufacturing and other fields. People have put forward higher requirements for the application of computers in drawing, engineering design, analysis and document production. Computer-aided design technology CAD (ComputerAided Design) was born. As the flagship product of the CAD industry, AutoCAD is currently the most widely used computer-aided drawing design software in the world. For example, in architectural de...
