基于ObjectARX提取AutoCAD中任意格式表格信息

Extracting Information from the Forms in AutoCAD Drawings Based on ObjectARX

针对AutoCAD图纸中的标题栏和明细表信息的提取,本文以Visual Studio 2008为开发平台,采用单元化表示信息和基表匹配的方式提取标题栏信息,并通过构建三元数组的文本信息矩阵表达明细表结构,完成明细表信息的提取。同时,采用基于动态链接库MFC设计ObjectARX应用程序,将最终提取出的表格信息通过ADO技术存储至SQLServer数据库中,程序运行结果表明,打开AutoCAD图纸后加载应用程序tqmxb,运行提取明细表命令,按照命令窗口提示进行操作,框选表格大体区域,即可完成全部提取操作。该研究为PDM系统的应用提供基础信息,对自动生成产品结构树,提高产品数据管理效率具有实际意义。

With respect to the study of extracting information from the title panel and material list in AutoCAD drawings, this paper uses Visval Studio 2008 as the platform. This paper presents methods of extracting information from the title panel by using the unit to describe the title panel and then using the base table to match with it. According to the expression of the material list by the three elements matrix, the paper finished extracting material list. The design of the ObjectARX program is based on MFC, and the finally extracted information is saved in SQL database through using access technology-ADO. The running result shows that all operations of the extraction can be completed by loading application tqmxb, and then running the orders according to the command window prompt. This study can provide fundamental information for PDM, which is very important for generating product tree and improving product data management efficiency.
