Design And Implementation Of Engineering Drawing File Management Platform

With the continuous development of computer technology,the engineering design technology has also taken place the huge change.The influence of CAD technology on engineering drawing design is growing.It affects many industries,such as bridge design,road design,aerospace design,electric power design,mechanical design and so on.CAD technology has fundamentally changed the traditional manual drawing models which rely on drawings to organize the entire production process of the technical management.New product design can be carried out quickly with the use of CAD technology,moreover,the use of CAD technology improves of design quality and decreases the design cycle of new products.That not only improves the competitiveness of enterprises in their industries,in addition,it has the beneficial effects on the transformation of the traditional industries,the rise and development of emerging technology industries,and the standardizationand internationalization of Chinese industries.AutoCAD is the most widely used CAD software in Windows and MAC systems.As we all know,files generated using AutoCAD software are in DWG format,however,Autodesk did not disclose the storage format of DWG files.So it is very difficult to parse.This has caused great difficulties to the information work of enterprises.Because engineering drawings not only describe the organization and shape of the product,they also contain a lot of information about the drawing themselves.For example,design time,design phase,designer,approval process and so on.Thses informations are very important to the information work of enterprises such as data collation and archiving.However,because of the huge difficulty of parsing the DWG format file,there is a gulf between the transformation of information management systems and engineering design drawings.Causes these text information to have to be entered manually,this operation is not only cumbersome but also inefficient.And there are still problems such as data can not be shared.In view of the above problems,this topic carries on the detailed function requirement design to the platform,secondary development of AutoCAD based on.NET has been accomplished.The platform has the functions such as CAD drawing recognition,catalogue generation,automatic printing,drawing splitting,audit management,graphic drawing recognition and so on.The traditional management mode of engineering drawing has been changed.It not only improves the efficiency and level of management.To a great extent,it also improves the sharing and accuracy of the information of engineering drawings.
