Embodiment Construction

[0040] The parts drawing drawn by AutoCAD are saved in dwg and dxf formats respectively, and the information database of the graphic title bar is established by using Access, the method of accessing the database is determined ODBC, and it is connected with the data source, and the dxf is extracted by Visual C++6.0 language programming Graphic element information in the file, store the data in the dxf file in the database and the set dynamic array, use the ActiveX control technology to realize the preview display of the dwg file, set the authority limit of the administrator and user, and realize the increase of the graphic database , delete, query, preview, pan and other operations. The overall block diagram of the system of the present invention is as figure 1 shown.

[0041]The establishment of the Access database, the integration of data forms the database, and the table is the basic unit of storing data in the database. Use Microsoft Access software to create the database...

Abstract

The invention discloses a management method of graphs based on dwg and dxf file formats and belongs to the technical field of document processing. The graph management method includes utilizing Access to build a graph title bar information database, determining a method for accessing the database as ODBC (open database connectivity), accessing the database on the basis of ODBC, enabling ODBC to be connected with a data source, extracting graphic element information in a dxf file through VisualC++, storing data in the dxf file into the database and a dynamic array which is arranged, building a three-view management interface, and using an ActiveX control to realize previewing display of a dwg file; performing addition, deletion, inquiry, previewing and translation on the graph database. Graph positioning is realized directly according to information of a graph title bar, the ActiveX control is combined, and an AutoCAD-based dwg and dxf file format graph database management system is development, so that quick, safe and effective management on graphs drawn by AutoCAD is realized.

Description

technical field [0001] The invention relates to a management method for graphics based on dwg and dxf file formats, which belongs to the technical field of document processing. Background technique [0002] With the continuous development and updating of computer technology, CAD technology has been widely used in engineering drawings and management activities. AutoCAD is an auxiliary drawing design system for personal computers developed by Autodesk Corporation of the United States. According to incomplete statistics, at present, 3 million people in about 90 countries in the world are using AutoCAD software to draw various drawings. One can imagine the large amount of computer drawing. [0003] Entering the 21st century, with the rapid development of electronics and microcomputer technology, and the highly developed information industry, document management is also undergoing tremendous and revolutionary changes in the wave of informatization. Under this new trend, how to ...
