Method of Inserting Barcodes in DWG Files Based on ActiveX Automation Technology

In order to implement information management precisely during the whole life cycle of drawings, a method of insertion barcodes in DWG files based on ActiveX Automation technology is proposed. The AcadDocument, AcadPolyline and AcadGroups objects of AutoCAD ActiveX Automation are used in the method to realize insertion of barcodes in DWG files interactively or automatically, and drawing versions are marked by the newest date of insertion of barcodes, then the DWG files are automatically converted to DWF files for browsing, checking and reviewing on Internet/Intranet. The proposed method has been applied to the developed document management system, operation results of the system show that the method is stable and effective.
