Collaborative design system for subway engineering based on dwg file splitting and reorganization method

Abstract

The present invention relates to a subway engineering collaborative design system based on the method of splitting and reorganizing DWG files, including a central database, a project database, and a local device, wherein the local device is used to extract from a design drawing file related to a certain engineering project Splitting the graphic elements, and uploading the graphic element data related to the graphic elements to the central database, the project database is used to store the design drawing files related to the engineering project, wherein, in the design drawing files, each The primitive has corresponding primitive data, primitive basic information and primitive update information, and the primitive data includes drawing information of the primitive, and the basic information of the primitive includes a handle of a primitive, a version of a primitive, and a mark of a primitive, The primitive update information includes primitive state. The invention has the following beneficial effects: the granularity of management is finer, reaching the first level of components, and at the same time, data redundancy is reduced, redundant system coordination work is reduced, operation is simple, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer-aided design of construction engineering, in particular to a subway engineering collaborative design system based on the method of splitting and reorganizing DWG files. Background technique [0002] At present, the mainstream working medium of subway station designers is still CAD (DWG) files. Designers are already very familiar with CAD work methods and file formats, and design delivery and communication are basically based on this file. [0003] The current management system saves and manages CAD files as a whole, and uses them as a whole when calling, and cannot extract useful parts of them. That is to say, through the exchange of dwg files, professional designers can directly set the drawings provided by others as a whole as a reference, or directly quote after modifying the drawings, so as to achieve the purpose of exchange and sharing. The above method has the following disadvantages: 1. D...

AI Technical Summary

Problems solved by technology

The above method has the following disadvantages: 1. As a whole, useful components cannot be extracted from the drawing; 2. There are many additional collaborative tasks, such as processing drawings; 3. Redundant drawing information
