摘　　要：为满足产品生产过程中使用设计图中的尺寸公差和技术规范进行现场质量检测和质量控制的需求,基于AutoCAD软件平台研究了工程图标注信息的筛选和提取方法。利用AutoCAD.NET开发工具,按照AutoCAD绘图中几何尺寸、形位公差、多行文本等标注方式,根据AutoCAD数据库中标注信息编码所包含的控制码和特殊字符,分别提取几何尺寸、公差、粗糙度和技术要求等;并建立与数据库的连接,存储到数据库中生成标注信息数据表。实验表明,该方法可以方便、完整地将工程图中的标注信息提取出来,便于用户使用和管理。In order to satisfy the requirement of on-site quality inspection and quality control by using the dimension,tolerance and specification within design drawings in the manufacturing process,a method is studied for screening and extracting dimension information in engineering drawing based on the AutoCAD software platform.Using AutoCAD.NET development tools,according to the marking methods of geometric dimensions,geometric tolerances and multi-lines of text in AutoCAD drawings,and according to the control codes and special characters contained in the labeling information coding in AutoCAD database,the geometric dimensions,tolerances,roughness and technical requirements are extracted respectively,and the connection with the database is established and stored in the database to generate labeling information data tables.The experimental results show that the method can extract the dimension information from engineering drawings conveniently and completely,which is convenient for users to use and manage.
